feat: auto-detect username from git/environment for write operations

Implements automatic username detection to eliminate annoying prompts
when performing write operations in the web UI.

Server-side changes:
- Added detectUsername() function that checks git config user.name,
  then environment variables (USER, USERNAME, LOGNAME)
- Falls back to "web-user" if no username found
- Username detected once at startup and passed to all templates

Frontend changes:
- Added initUsername() function to store server-provided username
  in localStorage (beady-username key)
- Updated all 6 templates to initialize username on page load
- Removed old prompt-based username collection from detail.html
  and issue_form.html

User experience:
- No prompts required - username auto-detected from git config
- Persistent across sessions via localStorage
- Consistent with git commit attribution

Closes beady-41
