chore: migrate oxlint config to e18e plugin and fix lint violations

- Replace root `eslint-plugin-lingui` jsPlugin with `@e18e/eslint-plugin`; move lingui rules into per-app `.oxlintrc.json` overrides for native and web
- Add `jsx-a11y`, `react-hooks-js` (native), and expanded lingui rule sets to per-app configs
- Add `oxc/no-barrel-file` warning at threshold 0 to root config
- Fix `e18e/prefer-url-canparse`: replace `try { new URL() } catch` with `URL.canParse()` in server-url screen and server lib
- Fix `e18e/prefer-timer-args`: pass callback args directly to `setTimeout` instead of wrapping in arrow functions (use-debounce, integration-card)
- Fix `e18e/prefer-static-regex`: hoist `/\/+$/` to module-level constant in server-url screen
- Fix `react-hooks-js/refs` and `react-hooks-js/set-state-in-effect`: convert `useRef` tracking patterns to `useState` + render-time derived updates in `use-server-connection`, `expandable-text`, and settings screen
- Fix `react-hooks-js/immutability`: extract stable palette sub-values before `useMemo` deps in title detail screen
- Apply `e18e` and other rule fixes across core, tmdb, web components, and i18n packages
