Add multi-instance support to 13 more services

Retrofits the standard multi-instance pattern (documented in CLAUDE.md)
onto actualbudget, filebrowser, fmd, homebox, immich, jellyfin, joplin,
lyrion, meshcentral, ntfy, rustdesk, unifi, and vaultwarden. First
instance of each keeps its original name/paths/ports unchanged; adding a
second instance prompts for a short name and auto-scans for free ports.

Service-specific handling beyond the base pattern:
- joplin, immich, unifi: dedicated Postgres/Mongo container per instance
  (not shared), matching the backup-isolation reasoning in CLAUDE.md.
- meshcentral, unifi: multiple fixed ports scanned/shifted together so
  they stay paired per instance.
- rustdesk: 6-port block shifted by a fixed offset per instance, since
  the image hardcodes its internal ports with no per-port env override.
- jellyfin: DLNA/discovery UDP ports only published for the first
  instance to avoid a host-wide fixed-port conflict.
- lyrion: first instance keeps network_mode: host (required for
  Chromecast/Squeezebox broadcast discovery); additional instances fall
  back to bridge networking with auto-scanned ports, trading away
  zero-config discovery since a second container can't also bind host
  networking's fixed ports.
- magicmirror.sh already had its own working multi-instance pattern
  (upfront instance count, numbered subdirs) and was left as-is.

Verified via bash -n on every changed file, plus scripted functional
runs (fake docker/ss) exercising first + second instance installs for
every port-scanning shape used here (single, dual-paired, quad-paired,
block-offset) and confirming dedicated per-instance DB naming and the
lyrion host->bridge compose output.

# First instance keeps the plain "rustdesk" name/paths/ports exactly as
# before (zero behavior change for anyone with a single instance). Only
# asking to add a second one introduces suffixed naming — same pattern as
# services/mattermost.sh and services/wordpress.sh. The 6 ports
# (21115-21119 TCP + 21116 UDP) are fixed *inside* the container — the
# image doesn't expose an env var to change them — so an additional
# instance shifts the whole host-side block by a fixed offset instead of
# scanning port-by-port, the same approach services/traccar.sh uses for
# its device-protocol range.
