Add migration options: copy, symlink, or use in-place

Browse Source 
When source is on mounted drive (/mnt/*, ~/drives/*, /media/*):
- [C] Copy - Copy to ~/docker (for old OS drive migration)
- [S] Symlink - Create ~/docker → source (for data drive)
- [U] Use in-place - Use source directly, no copy

This handles both scenarios:
- Old OS drive mounted temporarily → Copy
- Data drive you'll keep using → Symlink or use in-place
