Major improvements to drive detection and create-all command

Drive Detection Improvements:
- Enhanced discover_mounts() with verbose mode showing detailed disk info
- Better filtering to skip loopback devices and empty entries
- Extended SHARES array format to include device name and UUID (5 fields)
- Shows mount status, disk size, and free space for each partition

create-all Command Overhaul:
- Now a comprehensive 4-step setup process:
  1. Creates static shares (home + root)
  2. Detects all disk partitions on the system
  3. Automatically mounts unmounted disks to /mnt/<label>
  4. Adds disks to /etc/fstab for persistent mounting
  5. Creates Samba shares for all mounted disks
- Perfect for initial setup or bulk disk management

Other Improvements:
- discover command now shows verbose output with mount status
- auto-disks shows count of created shares
- Updated all functions to handle new 5-field SHARES format
- Better error handling and user feedback throughout

This makes FSA truly zero-touch for multi-disk setups!

+1. Create static shares (home directory and root filesystem)
+2. Detect all disk partitions on the system
