feat: add Syslog configuration to Network Services (v0.10.8 Beta)

New Syslog page under Network Services exposes RouterOS logging actions
and routing rules with full CRUD. Logging actions define destinations
(remote syslog server, memory, disk, echo); logging rules define which
topics route to which action.

Single Device and All Devices modes are functionally identical — All
Devices applies changes across every online device in parallel and
shows per-entry coverage badges indicating which devices have each
action or rule. Toggle enable/disable works in both modes.

Remote actions display address:port with facility/severity in a single
Destination column; memory/disk/echo rows show no irrelevant remote
fields. Syslog KPI card added to the Network Services overview.
