Fix macOS SMB mount: AAPL caps, credit grant, file_index, QueryDirectory padding

- AAPL: Restore UNIX_BASED+NFS_ACE server_caps, RESOLVE_ID+FULL_SYNC volume_caps (Samba baseline)
- Credit: Grant min 1 credit in dispatch response for smbclient compatibility
- file_index: Assign 1-based index per entry in list_dir (both VFS and local backends)
- smb_match(): Add wildcard pattern filter (*/?) for macOS single-entry QueryDirectory probes
- FILE_ID_BOTH_DIR_INFORMATION: Add 2-byte Reserved2 padding between ShortName and FileId
- macOS Sequoia 15.5 mount_smbfs now succeeds (tested: ls, cat, read)
