fix: update BitMacro project URLs to landing pages

Update relay-agent and relay-panel entries to point 
to their respective landing pages instead of GitHub repositories.

This allows nostr.net to resolve proper favicons and metadata for 
display in the directory cards.

- relay-agent → https://bitmacro.io/relay-manager
- relay-panel → https://relay-panel.bitmacro.io
