fix(i18n): Translate UI text built from template literals

Template literals such as `Remove data source '${name}'?` reached props and
calls that look text up exactly (dialog messages, labels, aria-labels, menu
items, action titles), so they always showed in English. Some notification
titles also spliced lowercase English words into a sentence.

- `tx` also works as a tag: tx`Remove data source '${name}'?` looks up
  "Remove data source '{name}'?" by its literal parts, fills in the values
  (translated when the catalog has them) and remembers the result, so the
  primitives that pass strings through `tx` translate it again after a locale
  change or once the catalog has loaded (actions registered at startup).
- 269 template literals at exact-lookup sites now use the tag; text that
  spliced words or plural suffixes is written as one sentence per variant
  (safe delete, Docker delete/prune, rebase, conflicts, VCS "No … in
  progress", database copy errors, inspection descriptions, ...).
- zh: 280 new entries; stale and duplicate-shape entries removed.
- textCatalog guard: untagged template literals at exact-lookup sites fail
  (with an allowlist for code-like text), tagged text is checked against the
  catalog by shape, case-changing values and `c ? "a" : "b"` suffixes inside
  translated templates fail, and a catalog may hold one entry per template shape.
