Tom Moor adbffc0734 chore: clear mechanical lint warnings (Phase 1) (#12198)
* chore: clear mechanical lint warnings

Drops 44 oxlint warnings (559 → 515) by fixing easy mechanical rules
across the codebase: no-useless-escape, no-duplicate-type-constituents,
no-redundant-type-constituents, no-unused-expressions,
no-meaningless-void-operator, require-array-sort-compare, await-thenable.

* chore: drop callback parameter from useCallback deps

The `open` argument is a parameter of the callback, not a closed-over
variable, so it doesn't belong in the deps array.

* chore: promote cleared lint rules to errors

Promotes the rules cleared in this PR from warn to error so future
violations fail the lint:

- no-unused-expressions
- typescript/await-thenable
- typescript/no-duplicate-type-constituents
- typescript/no-meaningless-void-operator
- typescript/require-array-sort-compare

Removes the override that suppressed no-useless-escape on source
files (the global rule is already error) and fixes the 21 escape
violations that this exposed in regex character classes and template
literals.

* chore: address PR review feedback

- usePinnedDocuments: simplify UrlId to plain string instead of the
  intersection trick.
- PlantUML embed: move - to end of character class so it's a literal
  hyphen rather than a range operator.
- checkboxes: type token params as Token | undefined to match the
  actual call sites that pass tokens[index - 2] etc.
