fix slowness of previous refactors that injected nostr-sdk into this codebase + refactors.

- adjusting many small things related to nostr-sdk usage
- fetching profiles in a smarter way
- decoupling the logic for rendering profile pages from the `grabData`/`getEvent` flow of other event pages.
- incorporating nostr-sdk more holistically, including more hints stuff
- improving nostr-sdk itself after some bugs and weird behaviors observed here
- set up opentelemetry (should probably remove this later)
