feat: add NIP-43 relay access metadata support

Add feed and detail rendering for kind 13534 (Relay Members) events,
and enable all NIP-43 kind constants for relay access management.

- Add RelayMembersRenderer with feed and detail views
- Enable kind constants: 13534, 28934, 28935, 28936
- Use Shield icon to represent relay access control
- Extract members from NIP-43's "member" tags (not standard "p" tags)
