chore: merge dev into main — main still calls backend routes deleted in backend-api#113

[pparage]

main still contains the five DefaultVms composables that call bundle routes removed from the backend in range42-backend-api#113 (now merged to backend dev). They build their URLs dynamically, so a literal path grep does not find them:

• src/composables/runnerCalls/bundle/core/proxmox/configure/DefaultVms/create.ts — BUNDLE_PATH = '/v0/admin/run/bundles/core/proxmox/configure/default', then `${endpointBase.value}/create-vms-${target_infrastructure_group}`
• .../DefaultVms/startStopPauseResumeVms.ts
• .../DefaultVms/delete.ts
• .../DefaultVms/snapshots/create.ts
• .../DefaultVms/snapshots/revert.ts

All five are imported and instantiated by src/views/ProjectEditor.vue.

dev is already clean — 773539d removed the whole tree. This is purely a branch-sync gap: deploying a main UI against a dev backend gives 404s on those calls. In practice they were only wired to a global loading indicator whose triggers were never connected, so user-visible impact is likely nil — but the mismatch should not sit there.

The same five files are also present in all four git stash entries (stash@{0} on pr-43, stash@{1..3} on feature/gamenet-authoring-v1); worth dropping or rebasing those before they get restored onto a branch.

Sequence: merge deployer-ui dev → main before any deploy that pairs a main UI with a dev backend.
