feat(obsidian): add choice between automatic search and manual browse

Problem: When clicking on a burg/marker, automatic search would run
immediately without giving the user an option to skip it and browse
manually. Users had to wait for the search to complete before getting
to the browse option.

Solution: Add initial dialog (showSearchMethodDialog) that appears
first, asking the user to choose:
- 🔍 Search: Run automatic search (FMG ID lookup + coordinate search)
- 📁 Browse: Skip search and go straight to manual browse/folder tree
- Cancel: Close without doing anything

Benefits:
- Users who want to browse manually can do so immediately
- Users who want automatic search can still use it
- No forced waiting for search when you know you want to browse
- Clear visual distinction between the two methods
- Folder tree is now just one click away

This gives users complete control from the very first interaction,
making manual browsing much more accessible.
