feat(verfahrensablauf): event-card overhaul — iconified state + caret-popover unhide (t-paliad-293)

m/paliad#125 — concern A (horizontal scroll) and concern B (compact
event-card UX).

Concern A: the inline "Wieder einblenden" chip from t-paliad-290 pushed
hidden cards past their column width on 375/414/768, causing horizontal
page scroll. Fix: drop the chip entirely; surface the un-hide as a
prominent "Wieder einblenden" entry inside the caret popover (matches
the m's "actions live in the caret menu" framing). The card title row
now also wraps + shrinks (flex-wrap + min-width:0 + overflow-wrap)
so no inline child can ever blow the row width.

Concern B (the bigger UX): cards now speak m's "cut the tree of
possibilities" vocabulary via iconified state markers in the title row:
  - Optional event → ⊙ (timeline-state-icon--optional)
  - Hidden by user → 👁⃠ (timeline-state-icon--hidden)
  - Conditional anchor → already covered by the "abhängig von <parent>"
    chip on the date column (t-paliad-289); no duplicate marker.
  - CCR-included / appellant picks → already on the per-card chip.

The legacy `.optional-badge` text chip and `.event-card-choices-unhide`
inline chip are gone — both replaced by the icon language + popover
entry.

Renderer wires the unhide path with two contracts:
  - data-is-hidden="1" on the caret button when isHidden=true, so the
    popover knows to render the prominent unhide block on top.
  - Defensive fallback: if a rule's choices_offered was edited away
    after the user had already saved skip=true (so isHidden=true but
    choicesOffered is empty), the renderer synthesizes {skip:[true,
    false]} so the popover still has an un-hide path.

CSS:
  - .timeline-item min-height 4rem → 2.75rem (less vertical air).
  - .timeline-content padding-bottom 1rem → 0.6rem (tighter gutter).
  - .timeline-item-header gains flex-wrap + min-width:0.
  - .timeline-name gains min-width:0 + overflow-wrap:anywhere
    (long German compounds wrap mid-word instead of overflowing).
  - New: .timeline-state-icon[--optional|--hidden] icon-style markers.
  - New: .event-card-choices-unhide-btn — prominent full-width lime
    pill inside the popover, midnight-text in both themes (matches
    the active-option pin from m/paliad#123).

i18n:
  - state.optional.tooltip — "Optionales Ereignis" / "Optional event"
  - state.hidden.tooltip — "Ausgeblendet — über Optionen-Menü wieder
    einblenden" / "Hidden — restore via the options menu"
  - choices.unhide.chip kept (now used as the popover button label).

Tests: 27 → 29 tests in verfahrensablauf-core.test.ts. Old isHidden
inline-chip cases replaced by state-icon + caret-data-is-hidden
contract cases. Added defensive-fallback case for the synthesized
skip offer. Added regression guard that the legacy
.event-card-choices-unhide class is no longer emitted. Added
optional-priority → ⊙ icon contract pair.

Hard rules respected:
  - Title + date + Rule citation unchanged (m likes these).
  - Click-to-edit on date span (.frist-date-edit) untouched.
  - Conditional rendering (t-paliad-289 chip + dotted border) untouched.
  - Per-card actions (skip, appellant pick, include-CCR, unhide) all
    reachable via the caret popover.

+--
+-- m's 2026-05-25 report: the upc.dmgs.cfi proceeding stops at the
+-- last party submission (rejoin) — no interim conference, no oral
+-- hearing, no decision row, no appeal-spawn. The upc.pi.cfi
+-- proceeding has its decision row (`pi.order`) but no spawn into
+-- the appeal tree. Both gaps prevent the Verfahrensablauf timeline
+-- from rendering the court phase plus any downstream appeal sub-
+-- tree that atlas's #96 spawn-rendering mechanism is otherwise
+-- ready to surface.
+--
+-- Two sections in one migration (slot 133 — knuth on 132, paliadin
+-- coordinated):
+--
+--   A. UPC Damages tree-end rows (#117)
+--      A1  upc.dmgs.cfi.interim       UPC RoP R.105   court-set hearing

+-- Source citations:
+--   * docs/research-deadlines-completeness-2026-05-25.md
+--       — §2.1 (upc.dmgs.cfi has only 4 rules: R.131.2 / R.137.2 / R.139)
+--       — §D Damages table (R.144 tree-end row missing — listed
+--         in Tier 4 as "cosmetic", upgraded to Tier-0 by m's
+--         report once the wider follow-up gap was understood)
+--   * docs/audit-upc-rop-deadlines-2026-05-08.md §D row R.144,
+--     §F R.220.1(a) / R.224.1(a) (verified verbatim in youpc DB
+--     under law_type=UPCRoP).
+--   * UPC Rules of Procedure (consolidated):
+--       R.105 — Interim conference (court fixes after written
+--         procedure closes; same structural shape as the inf
+--         interim conference, already modelled as `upc.inf.cfi.interim`).
+--       R.118 — Decision after oral hearing; general rule for
+--         deciding panels.
+--       R.250 — Determination of damages decision; damages-
+--         specific decision rule (chains R.144 indication →
+--         damages award).
+--       R.144 — Final decision on damages quantum (tree-end
+--         anchor for §A3).
+--       R.220.1(a) — Appeal lies from any final decision /
+--         decision disposing of the case at first instance.
+--         A PI order under R.211 disposes of the urgent question
+--         and is therefore appealable on the main 2-month track
+--         (not the 15-day order track of R.220.1(c), which covers
+--         case-management and procedural orders requiring leave).
+--         Curie's §F table confirms the main-track wiring for
+--         decisions on merits / disposing orders.
+--       R.224.1(a) — Statement of Appeal within 2 months of
+--         service of the final decision; the deadline-notes text
+--         mirrors mig 095's inf.appeal_spawn / rev.appeal_spawn.
+--       R.224.2(a) — Statement of grounds within 4 months
+--         (separate deadline in the spawned upc.apl.merits
+--         proceeding; already present as upc.apl.merits.grounds).
+--
+-- Shape decisions (mirroring mig 012 / mig 095 conventions):
+--   * Court-set rows (interim / oral / decision) carry
+--     primary_party='court', event_type='hearing'|'decision',
+--     duration_value=0, is_court_set=true, parent_id=NULL,
+--     concept_id reuses the shared concepts already wired for
+--     upc.inf.cfi (interim-conference / oral-hearing / decision).
+--   * Spawn rows carry primary_party='both', is_spawn=true,
+--     spawn_proceeding_type_id=11 (upc.apl.merits), spawn_label
+--     identical to the merits spawn already in production. The
+--     spawn row's parent_id is the spawning decision/order row
+--     (so the audit log carries the trigger link).
+--   * No condition_expr — m's F2.3 decision recorded in mig 095
+--     §3: "the appeal deadline should always be triggered by a
+--     decision … appeal is always a possibility." Visibility
+--     filtering on the frontend hides appeals on projects where
+--     no appeal is contemplated.
+--   * sequence_order numbering follows the inf convention
+--     (40=interim, 50=oral, 60=decision, 80=appeal_spawn) so the
+--     Verfahrensablauf timeline orders consistently across
+--     proceedings. For PI the existing pi.order sits at
+--     sequence_order=3; the appeal_spawn lands at 10 (clear of
+--     the writ phase, room for future court-phase rows).
+--
+-- Idempotency: every INSERT is gated by `WHERE NOT EXISTS (… same
+-- submission_code, proceeding_type_id, lifecycle_state)`. Re-apply
+-- against an already-migrated DB inserts zero rows and the audit
+-- log carries no duplicate entries.
+--
+-- audit_reason set_config required at the top — the mig 079 trigger
+-- on paliad.deadline_rules raises EXCEPTION 'audit reason required'
