ESLint --fix: auto-fix brace-style, indent, semi, no-trailing-spaces

Run eslint --fix across src/ to clear ~1900 mechanical lint errors
surfaced by the @typescript-eslint v8 + react-hooks v7 + react-compiler
upgrade in the React 19 modernization PR.

Issues fixed automatically:
- brace-style (Allman): try/catch one-liners reformatted to multi-line
- indent: tab-vs-space and depth corrections
- semi: missing trailing semicolons
- no-trailing-spaces

No semantic changes. Remaining 701 errors are real-code issues
(set-state-in-effect, rules-of-hooks, no-unsafe-* type checks) that
need manual per-file review.
