fix(warm): revive the editor draft when write access arrives late (#756)

A same-route remount that cannot edit yet - hass arrives after the
element is inserted (the demo's own order), or a non-admin waits for the
server's can_write - keeps the editor in _pendingNavMode and enters it
later through _resumePendingNavMode -> _setMode. The draft revival was
wired only into the immediate warm adoption (_requestMode(..., adopt)):
on the pending path the draft was lost, _warmRevivePending stayed up for
the instance's life, _warmSnapshot stopped writing dlg, and the next
remount brought back the predecessor's stale draft.

The adoption tail (draft revival once under a held refit, then the
settled stage as the refit baseline) is shared by both paths: the
sequencing lives in src/warm-mode-adoption.ts, the refit bookkeeping in
the card's _holdWarmRefit/_releaseWarmRefit. The pending mode still enters through _setMode, the transition
authority smoke_nav_persist holds it to; resumeWarmMode then settles the
revival. _setMode ends the passive boot grace and refits the camera to
a header measured before the editor chrome rendered, so a camera the
pending window left untouched is put back and held exactly as an
immediate adoption holds it; a camera that has already moved on (View
refit, the user's pan, another space) is left to the ordinary refit. A
mode that did not commit, an explicit mode command in the pending window
and a route departure settle the revival too: no outcome leaves
_warmRevivePending up. The core file gives back 4 lines.

smoke_warm_dialogs gains section H through the UI: the three late-write
orders keep mode, draft, dirty baseline and a frame-by-frame identical
viewport; the chain carries this instance's draft, not the predecessor's;
a space switch in the pending window eats the draft. 14 checks are red
on dev. The mutant warm-pending-mode-leaves-revive-waiting is guarded by
the smoke; docs/WARM-REMOUNT.md §2 describes the pending editor.
