Perk-a-cola redesign + surface RCON map/gametype/roster/health

Themes the fleet manager around the Electric Cherry perk-a-cola from Mob of
the Dead — cherry-red art-deco label with electric cyan discharge. New
design tokens (Alfa Slab One + Inter + JetBrains Mono, self-hosted), full
redesign of layout/dashboard/cards/detail page, tokens pass on
deployments/betas/pipeline/beta/diff, cherry+lightning favicon.

Lights up server data that RCON was already fetching but the UI dropped.
parsePlayerRoster() extracts num/score/ping/guid/name from both status
dialects. Worker persists last_map/last_gametype/last_roster/last_seen_at/
last_error (new columns with idempotent boot-time ALTERs) and emits them
over SSE. Fleet cards now show health dot, map · gametype, top-3 roster
preview, and last-seen. Detail page adds a sortable full roster with
distinct empty-lobby vs offline states. New health classifier
(online/stale/offline) drives the visual state.
