About 270 UI strings were JS template literals with interpolation passed to exact catalog lookup, so they could never be translated; about 25 more spliced lowercase English fragments into sentences.
`tx` now also works as a template tag (`` tx`Remove data source '${name}'?` ``): it looks up the entry by the literal parts (`{name}` placeholders), translates interpolated values that have entries, and remembers generated text so it re-translates after a language switch or when the catalog loads later. Call sites use the tag; spliced fragments are written as whole sentences per variant. Adds 280 Chinese translations and removes stale ones.
The catalog guard now also fails on untagged template literals reaching exact lookup (unless allowlisted with a reason), tagged text missing from the catalog, case-changed or ternary-suffix interpolations, and duplicate template patterns.

Root causes: Typo "Change to" replaced one occurrence even for declared names (breaking references); inspections had no Disable / Edit settings controls anywhere; en_US Hunspell does not derive agent nouns like "checkpointer" and compound identifier words were flagged; local inspections (Typo, file references, SQL) never reached Problems.
Fix (IDEA): "Typo: Rename to…" renames via LSP rename, falling back to syntax-based local rename, never a silent single replace, and lists identifier-safe words only; intention submenu (→) with Edit inspection profile setting / Disable inspection for every inspection; Problems and Inspection Results get Disable Inspection, Change Severity, Edit Inspection Profile Setting; Typo options Process code / literals / comments; -er/-ers derivation and identifier compounds accepted, common misspellings still flagged.
Siblings covered: all LSP and built-in inspections' intentions, file reference and SQL inspections in Problems, severity counter.
Verified: ide-spell tests (issue examples + ~50 real misspellings), vitest (286), in-app on macOS: only 'mesage' flagged, submenu, Rename to → 'message' updated both occurrences.
