fix: auto-insert space before @mentions when needed

Browse source 
- Auto-insert space before @ when dragging/dropping files after text
- Auto-insert space before @ when using mention insertion after text
- Maintains regex restriction from PR #7876 to prevent parsing in pasted logs
- Added comprehensive tests for the new behavior

Fixes #8063
