chore: repo-wide bloat sweep, remove dead code and fold duplicate helpers (#2150)

* chore: repo-wide bloat sweep, remove dead code and fold duplicate helpers

Remove 33 dead files, ~270 unreferenced exports/types, 13 dead i18n
namespaces and 4 unused dependencies; fold byte-identical helper copies
into one canonical home each (lib/utils chunk/sleep/utcDateStamp,
lib/dates/iso, lib/invariants/uuid, lib/xml/escape, lib/reports/sru/format,
lib/pdf/number-text, lib/browser/panel-request, lib/api/v1/body +
v1ValidationError rolled out to ~55 v1 routes, booking-template schemas).

No behaviour change: v1 bodies and status codes, MCP tool schemas, DB
writes and money math are untouched. Naive ore rounding was deliberately
not swapped for roundOre; see DECISIONS.md 2026-09-02 for the full list
of things left alone on purpose.

tsc, lint, 19588 unit tests and check:guards green; antipattern baseline
ratcheted (naive-ore-round 622 -> 620, hand-rolled-invariant 115 -> 113).

* test(transactions): import RawTransaction from @/types after the ingest re-export removal

CI's type ratchet (check:types, full tsconfig) caught the one test file
that still imported the type through lib/transactions/ingest.
