Remove unused import flagged by CI lint, then harden the toolchain so
such issues are caught before push:
- lint-staged now also matches .tsx/.jsx (previously .tsx files skipped
the pre-commit eslint pass, which is how the error reached CI)
- eslint ignores generated client bundles (gitignored, not worth linting)
- typecheck now also runs the client tsconfig; the hand-written browser
source was excluded from the root config and never type-checked
- consolidate the window global augmentations (showToast,
parseJsonResponseOrThrow) into a single client globals.d.ts; the inline
declare-global blocks failed (non-module files) and masked real errors

Moves the inline JS template literal from emails.tsx into a typed
TypeScript source file. The dynamic feedId value (previously interpolated
directly) is now passed via a window.__APP_CONFIG__ bootstrap script
injected immediately before the compiled static script in the HTML.
