feat(submissions): Composer Slice C — building blocks library (m/paliad#141)
Per the design at docs/design-submission-generator-v2-2026-05-26.md §8
and the Q2 / Q9 ratifications:

- Q2 (m, 2026-05-26): building blocks are plain text paste sources.
  No building_block_id reference is stored on submission_sections.
- Q9 (m, 2026-05-26): four visibility tiers — private / team / firm
  / global.

Schema (mig 149):

- paliad.submission_building_blocks — library catalog. Columns: slug,
  firm (NULL = cross-firm), section_key (binds to one section kind),
  proceeding_family (NULL = any), title_de/_en + description_de/_en
  + content_md_de/_en, author_id, visibility (CHECK in 4-tier set),
  is_published, created_at, updated_at, deleted_at (soft delete).
  RLS: coarse-grained SELECT — every authenticated user sees
  non-deleted non-private rows + own private rows. Tier-specific
  predicate (private/team/firm/global) applied in Go-layer service so
  semantics evolve without RLS migrations. Mutations admin-only (no
  RLS write paths).

- paliad.submission_building_block_admin_versions — append-only
  history per block, retention=20. Admin-side only; NOT referenced
  from submission_sections (per Q2's plain-text-paste model). Exists
  so accidental delete / overwrite are recoverable.

Backend:

- internal/services/submission_building_block_service.go (~510 LoC):
  BuildingBlockService. ListVisible applies tier predicate at query
  time (private = author_id match; firm = firm column NULL OR matches
  branding.Name; team = author shares a project_team with caller via
  paliad.project_teams self-join; global = open). ListAllForAdmin
  drops the predicate. Create + Update + SoftDelete + RestoreVersion
  all transactional; appendVersionTx writes one audit row +
  GC-deletes anything past the retention=20 horizon in the same tx.
  InsertIntoSection (the paste mechanic) clones content_md_<lang>
  into the section row with a "\n\n" separator if section already has
  content. NO building_block_id stamped per Q2.

- internal/handlers/submission_building_blocks.go (~480 LoC): nine
  handlers split between the lawyer-facing picker (list, insert) and
  the admin editor (list, get, create, update, delete, list-versions,
  restore-version, page). buildingBlockUpdateInput uses presence-
  tracking UnmarshalJSON for the four nullable fields (firm,
  proceeding_family, description_de/_en) so PATCH can distinguish
  "no change" from "set to null".

- Routes registered: lawyer-facing under /api/submission-building-blocks,
  admin-gated under /api/admin/submission-building-blocks/* and
  /admin/submission-building-blocks (page).

- Wiring: handlers.Services + dbServices + cmd/server/main.go all
  gain SubmissionBuildingBlock. NewBuildingBlockService takes the
  branding.Name firm hint for the visibility predicate.

Frontend:

- frontend/src/admin-submission-building-blocks.tsx (~85 LoC):
  three-pane admin shell (list / editor / version log) registered
  in build.ts.

- frontend/src/client/admin-submission-building-blocks.ts (~370
  LoC): admin client — list paint, edit form (slug + firm +
  section_key + proceeding_family + title/desc/content per lang +
  visibility radio + is_published toggle), per-block version log
  with restore button. Bilingual labels.

- frontend/src/client/submission-draft.ts: per-section "+ Baustein"
  button on the Composer editor toolbar (Slice B substrate gets one
  more affordance). openBlockPicker opens a modal filtered to the
  section's section_key, 200ms-debounced search by free text against
  title/description/content. Click a hit → POST insert-into-section
  → section row's content_md_<lang> gains the block's content
  appended at the end (Q2's plain-text paste semantic, no lineage).

- ~240 LoC of CSS: modal overlay + picker rows with tier-colored
  visibility chips + admin editor 3-pane grid + form rows + version
  list.

- 12 new i18n keys × 2 langs (admin.building_blocks.*).

Tests:
- TestValidVisibility (8 cases including case-sensitivity + empty).
- TestAppendBlockContent (8 cases covering empty-existing / empty-
  addition / whitespace-only / trailing newline collapse).
- TestBuildingBlockVisibilityConstants pins the 4 string literals
  against drift (RLS predicate + DB CHECK depend on them).

Build hygiene: go build/vet/test -short clean; bun run build clean
(2906 i18n keys, data-i18n scan clean).

Hard rules per ratifications honoured:
- Q2: no building_block_id lineage on sections (paste is plain text).
- Q9: 4 visibility tiers (private/team/firm/global).
- NO behavior change for pre-Composer drafts (the picker just doesn't
  show — section list is hidden for base_id NULL drafts).
- {{rule.X}} aliases preserved (block content goes through the same
  v1 placeholder pass on export as section prose).

NOT in scope per Slice C brief:
- User-authored private blocks (Slice C ships admin curation only;
  any-user create is a follow-up).
- Tier promotion review workflow (admin sets tier directly today).
- Per-section "where is this block used" reverse lookup (no lineage
  to query).
- Slice D's rich-prose features (headings, lists, blockquote) still
  Slice D's job; this Slice doesn't extend the MD walker.
