fix: optimize nx cache config for build:site, test, and e2e targets

- Exclude .next/cache from build:site outputs to reduce cache bloat
- Remove unused dist output from build:site (docs uses .next)
- Exclude non-build files (sqlite.db, .env*, coverage) from build:site inputs
- Fix test/e2e dependsOn to use build deps instead of cascading test/e2e deps
