Promote as a real deployment; version state and scope dropdowns

Turns promotion into a first-class deployment (action='promote') so it lands
in the deployments UI with before/after content, per-server restart tracking,
and one-click rollback. Non-beta matching-scope servers get restart_state=
pending so the existing sweep drains and restarts them the same way drift does.

Also adds a per-version state (untested/tested/test-failed) so the upload
flow can visibly signal that a beta must land before promotion, and swaps
the scope-value text box for game/map dropdowns populated from the fleet.
Beta rollback at ready-promote is now labelled Reject and marks the version
test-failed.
