refactor(schema): rename received_items and timesheets to their real names

RECEIVED_ITEMS -> DELIVERY_NOTE_ITEMS (55 rows): they are the lines on a
delivery note; the old name described an event, not a thing.

TIMESHEETS -> TIMESHEET_ENTRIES (1367 rows): this collection is the time
log, not a timesheet. The name is freed for the uploaded-document
collection created in Task 6.

PocketBase stores relations by collection id, so every relation survived
untouched; row counts asserted intact on both renames.

Two call sites the plan missed: src/app/api/timesheets/import/route.ts
and src/lib/ocr-result-tier.ts. Deliberately preserved the "timesheets"
string literals in pb-types.ts and the import route — those are
data_import_batches.batch_type select values, not collection names, and
changing them would have violated the select constraint.

+Rename two collections as part of the ingestion restructure.

+  python3 scripts/migrations/2026-09-12-rename-collections.py [--apply]
+
+DRY RUN BY DEFAULT. Pass --apply to rename.
+
+  RECEIVED_ITEMS -> DELIVERY_NOTE_ITEMS
+      They are the lines on a delivery note. The old name describes the
+      event, not the thing.
+
+  TIMESHEETS     -> TIMESHEET_ENTRIES
+      This collection is the time log (employee, date, hours, site), not
+      a timesheet. The name is freed for the uploaded-document
+      collection created in Task 6.
+
+WHY THIS IS SAFE
+----------------
+PocketBase relations store collectionId, not name, so every existing
+relation survives a rename untouched. Collection names are
+case-insensitive, so lowercase call sites in `src/` keep resolving until
+the code is updated - the rename and the code change do not have to be
+simultaneous.
+
+THE SAFETY PROPERTY
+-------------------
+A rename must move a name and nothing else. So each rename asserts, on
+the collection id it just patched, that the new name stuck AND that the
+row count is byte-identical to the count read immediately before. A
+count that moves means something other than a rename happened, and the
+run stops there rather than carrying on to the second collection with
+an unexplained delta behind it.
+
+Refuses to rename onto a name that is already taken by a different
+collection. Idempotent: a collection already carrying the new name is
+reported and skipped.
