feat(keyserver): add VKS/HKP messages and fixes

- add VKS/HKP messaging: warn about unverified publish and HKP upload
- add message when key server returns no key and retrieval errors
- update key upload/update result strings and adjust source refs
- clarify default server behavior: use default server for pub/refresh
- extend fingerprint validation to accept 16, 40 or 64 hex digits
- add search UI labels: (no user ID published), Unknown, Never
- update translations for multiple locales and mark old texts vanished
