fix: request NIP-46 permissions for bunker signing

- Add explicit signing permissions for event kinds: 5, 7, 17, 9802, 30078, 39701, 0
- Add encryption/decryption permissions: nip04_encrypt/decrypt, nip44_encrypt/decrypt
- Improve error messages when bunker permissions are missing or denied
- Add debug logging hint for bunker permission issues in write service
- This ensures highlights, reactions, settings, reading positions, and web bookmarks all work with bunker
