Web fix: deterministic feature strings, suggest_category vectors, raw bodies in the fake server

- Root cause of the raw keys (web_accounts_load_failed, the settle missing state) on main:
  Vitest 5's file-system module cache (on by default) skips only modules whose source
  contains the literal `import.meta.glob(`. catalog.ts wrote `import.meta.glob<…>(`, so
  its transform was cached by its own content and kept the glob result from before a
  feature added its i18n/*.json; the main checkout's node_modules/.vitest-cache served
  that stale catalog until a config change invalidated it. Fresh worktrees passed.
- catalog.ts: glob without a type argument (typed by annotation), with the reason.
- catalog.test.ts: the loaded feature catalogs must equal the i18n files on disk.
- A string two features render moves to the shared catalog: web_accounts_load_failed
  (accounts/PageStates, also rendered by Home) is now web_ledger_load_failed in
  src/i18n/web-strings.csv; sv.json/en.json regenerated.
- vectors.test.ts: suggest_category is PORTED and runs against features/expenses/suggest.
- fakeServer: bodies by Content-Type (JSON parsed, text/* as text, else raw bytes);
  ProfilePage's picture test asserts the uploaded bytes.
