Rework as scripts-centric, upload-only, gated beta lifecycle

Scripts become first-class: named, versioned, uploaded via the UI, optionally
scoped to a game or map. Any change that would land on scope-matched servers
(marking-required or new version of a scoped script) must first pass a beta.
The beta runs a per-server state machine — deploy -beta.gsc → wait empty →
Komodo restart → wait healthy → optionally wait for a real match end
(games_sp.log 'ExitLevel: executed') — before it's eligible for promotion.
Rollback is always available and restores from .OLD.

The shared/scripts mirror and its betas/ staging folder are gone. Every
server now has a tracked script inventory (server_scripts table), populated
only by explicit upload flows.

New: /scripts, /scripts/[id], /betas/[id] UI; /api/scripts + /api/betas +
/api/servers/[name]/scripts endpoints; scripts.ts, inventory.ts, beta.ts
(rewritten), beta-runner.ts, match-log.ts, komodoInspectHealthy().
Removed: push.ts, /api/push, BetaPanel, legacy importer.
