Add interactive volume path updates during migration

Browse Source 
Step 6 now scans docker-compose files for volume mounts:
- Detects absolute paths that don't exist on new system
- Shows old path and suggests ~/drives/primary/{folder}
- User can: accept suggestion, skip, or enter custom path
- Updates compose file with new path
- Creates directory if needed

Example:
  Container: immich
  Old path:  /home/user1/media/driveb
  Suggested: ~/drives/primary/driveb
  [Enter] Accept | [S] Skip | [path] Custom

### What Migration Does
1. **Scans source directory** - Auto-detects Docker directories, finds all compose files
1. **Scans source directory** - Auto-detects Docker directories on OS and mounted drives
2. **Shows containers found** - Lists each container with size
3. **Select what to migrate** - Whiptail checklist or text menu
4. **Stops containers** (optional) - Ensures clean copy of databases
5. **Copies containers** - Preserves versions, configs, and all data
6. **Starts containers** - In the new location
7. **Offers additional services** - Continue with normal install for more apps
5. **Migration method** - Copy, Symlink, or Use in-place (for mounted drives)
6. **Updates volume paths** - Detects old paths, suggests new ones, updates compose files
7. **Starts containers** - In the new location
8. **Offers additional services** - Continue with normal install for more apps
### Volume Path Updates
When migrating, the script detects volume mounts that don't exist on the new system:
```
Container: immich
Old path: /home/user1/media/driveb
Suggested: ~/drives/primary/driveb
Options:
[Enter] Accept suggested path
[S] Skip - keep original path
[path] Enter custom path
```
- Scans all docker-compose.yml files for absolute volume paths
- Only shows paths that don't exist on the current system
- Suggests `~/drives/primary/{folder}` as default
- Updates the compose file and creates the directory
