chore(deps): align Angular packages on 21.2.19

[4gray]

Summary

• align Angular runtime, compiler, CLI, DevKit, and schematics packages on 21.2.19
• refresh the pnpm lockfile for the synchronized Angular toolchain
• carry the required local Vite transform-filter patch forward from Vite 7.3.5 to 7.3.6

This replaces #1368 and #1369 and supersedes the Angular portion of #1373.

Testing

• pnpm install --frozen-lockfile
• pnpm nx build web --skip-nx-cache
• pnpm nx build electron-backend --configuration=production --skip-nx-cache
• pnpm nx run-many --target=lint --all --parallel=3 --output-style=static --skip-nx-cache
• pnpm run typecheck:ci
• pnpm run deps:nx:validate
• pnpm run deps:vite:test
• pnpm run release:notes:validate
• full all-project unit run: every project passed except one web beforeEach timeout under parallel load; isolated full web rerun passed 31/31 suites and 199/199 tests

Release notes

No release note: this is dependency maintenance with no intended user-visible behavior.
