fix: resolve layout and relay selection timing issues

Layout fixes:
- Remove conditional flex-1 from ProfileViewer profile content
- Remove conditional flex-1 from EventDetailViewer rendered content
- Main content sections now use natural size, only spell tabs have flex-1
- Prevents stacked headers issue and competing flex layouts

Relay selection fixes:
- Wait for appliedFilter to be resolved before selecting relays
- Ensures relay selection happens AFTER variable substitutions (, , etc.)
- Add appliedFilter check in finalRelays for all viewers (Profile, Event, Relay)
- Prevents relay selection with empty/incomplete filters
