MarekWo 2e009b2d3e refactor(dm): Show all contacts in DM dropdown selector
Changed DM approach from conditional button visibility to showing all
available contacts directly in the DM page dropdown. This provides better
UX and performance.

Changes:
- Reverted conditional DM button visibility in app.js (button always shows)
- Removed contacts loading from main page (app.js)
- Added loadContacts() function to dm.js to fetch contacts from API
- Modified populateConversationSelector() to show:
  1. Existing conversations (with history) first
  2. Separator: "--- Available contacts ---"
  3. All contacts from device who aren't in conversations yet
- Users can now start new DM conversations with any contact
- Updated README.md with new DM workflow description

Benefits:
- Simpler and more intuitive UX
- Better performance (no checks on every message)
- Users can proactively start conversations
- Clear visibility of who's available for DM
