v0.27.0:0 - in-app settings gear + swap-lock route fix

Move the ~20 optional cluster knobs out of the StartOS "Configure Sparks"
action (now just the 4 required fields) and into a dashboard ⚙ Settings gear,
backed by a /data/app_settings.json overlay keyed by env-var names. One shared
mutable Settings instance + Settings.reload() applies edits live without a
restart; existing installs' values migrate automatically on first boot.

Also: support-service ports (parakeet/kokoro/embed/qdrant + vllm) are now
configurable, and GET /api/swap/lock no longer 404s (it was shadowed by the
/api/swap/{job_id} catch-all). WebhookNotifier is re-pointed on save so its
url/secret reload live too.

-      "v0.26.0:0 — the model menu is now what's actually on your Sparks. The dashboard scans both Sparks for downloaded models and shows exactly those — no more hard-coded list. (1) Delete means delete: removing a model frees its weights AND takes the card off the menu (re-download later to bring it back, with its saved settings). (2) Download a new model and it appears on the menu by itself when it finishes. (3) Models Spark Control doesn't recognize show a \"needs setup\" card — the first time you switch to one, it reads the model's own files, guesses how to launch it (which family, solo vs both Sparks, the right vLLM flags), and asks you to confirm once; after that it's a normal card. (4) The download box now autocompletes known-good models. (5) Each install shows its own Sparks' models, so a shared copy no longer displays someone else's list. Removed the two legacy Qwen entries (235B FP8, 2.5 72B) — they'll still appear if you actually have them downloaded. No consumer-API changes; the /v1 proxy and swap API are unchanged.",
+      'v0.27.0:0 — settings move into the dashboard, plus two bug fixes. (1) New ⚙ Settings gear in the dashboard: all the optional cluster knobs — vLLM and support-service ports, container names, Parakeet/Kokoro/embeddings/Qdrant hosts, Open WebUI link, NGC key, swap webhook — are now edited here, in plain English, and apply immediately without a restart. The StartOS "Configure Sparks" action is now just the four required fields (two Spark IPs + SSH users); your existing optional values migrate into the gear automatically on first launch, and the settings are stored on the server and included in StartOS backups. (2) NEW: support-service ports are now configurable. If your vLLM runs on 8000 (vLLM\'s own default) and you moved Parakeet to another port, set them under ⚙ Settings → that fixes the false "vLLM down" and the Parakeet 404 some setups saw. (3) Bug fix: GET /api/swap/lock returned 404 (a routing bug where it was shadowed by the swap-job lookup); the swap reservation status now reads correctly. No breaking consumer-API changes; the /v1 proxy and swap API are unchanged.',
