Improvements: remove dead config, fix ESM, add URL validation, unify types, add missing logging

- Remove .prettierrc (dead config, Biome replaces Prettier)
- Rename lighthouserc.json to lighthouserc.cjs with module.exports for ESM compat
- Add logger.warn to empty catch blocks in auth, register, site-settings, prisma-cache, redis, security, rate-limit
- Unify ActionResult type: action-helper.ts uses 'ok' consistent with safe-action-shared.ts
- Add noUnusedLocals + noUnusedParameters to tsconfig + fix 25 pre-existing unused vars
- Replace barrel export src/types/index.ts with direct @/types/common imports
- Make trustHost conditional (development only) in auth.ts
- Add pre-flight URL validation to update-Nitrov3.sh to catch image.library.url misconfigurations
- Improve NITRO_IMAGE_LIBRARY_URL content validation in pre-flight & post-compute checks
