Share the excluded-ranges filter with IP Addresses; add Admin Links page

IP Addresses (IPAM) now reads the same excluded-ranges setting the
Consistency page manages, so "not interesting" addresses - a Docker
bridge network repeating on every host, say - can be hidden there too.
Adds a "Hide excluded addresses" toggle (on by default, with a live
count), an inline ranges editor matching Consistency's, an "excluded"
badge on rows shown anyway, and a per-row "Exclude..." shortcut that
suggests a /24 (or /64 for IPv6) around that address. Editing ranges
from either page updates both, since it's one shared setting.

Also adds Operations > Admin Links: a single page summarizing every
admin bookmark added across all servers (Dockge, Webmin, Cockpit, etc,
previously only visible per-server on each server's own detail page),
sortable and searchable, with the same add/edit/delete capability -
adding one here just asks which server it belongs to.

Verified both with real HTTP-level tests: a genuine Express app, a
scratch SQLite DB, and forged sessions, covering the exclusion
matching, the shared-setting round trip, the links aggregation and
join, and role enforcement - the real dev DB was confirmed untouched
throughout. Both packages build clean.
