On a CCR sub-project the SmartTimeline renders the parent inf project's
rules in the parent_context lane (correct — the CCR depends on the inf
schedule). Clicking "Datum setzen" on those rows bubbled up as a
generic "Konnte das Datum nicht setzen." because RecordAnchor only
looked up the rule under the CCR's own proceeding_type_id; for an
inf rule like upc.inf.cfi.soc that returned sql.ErrNoRows and dropped
into the catch-all error.
The anchor handler now mirrors the read view's broader rule scope: on
sql.ErrNoRows for a CCR project, we retry the lookup against the
parent project's proceeding_type_id. If the rule is found there, we
reject with a new CrossProceedingAnchorError carrying the parent
project's id + title so the frontend can render a clear DE/EN message
and a clickable link back to the parent ("anchor it on the
infringement proceeding, not the counterclaim"). We deliberately do
NOT auto-route the write across projects — that would silently mutate
the inf project's actuals and is out of scope per the brief.
Genuine "unknown submission_code" failures still surface as
ErrInvalidInput; the predecessor_missing 409 path keeps its existing
shape (the two errors discriminate on the response's `error` field).
Adds a Live-DB integration test that seeds an inf-only rule + a CCR
under a real inf project and verifies all three paths: CCR rejects
cross-proceeding, parent inf project accepts the same code, unknown
codes still report unknown_submission_code.
