add ability to disable cloud (#14221)

* add ability to disable cloud

Users can now easily opt-out of cloud inference and web search by
setting

```
"disable_ollama_cloud": true
```

in their `~/.ollama/server.json` settings file. After a setting update,
the server must be restarted.

Alternatively, setting the environment variable `OLLAMA_NO_CLOUD=1` will
also disable cloud features. While users previously were able to avoid
cloud models by not pulling or `ollama run`ing them, this gives them an
easy way to enforce that decision. Any attempt to run a cloud model when
cloud is disabled will fail.

The app's old "airplane mode" setting, which did a similar thing for
hiding cloud models within the app is now unified with this new cloud
disabled mode. That setting has been replaced with a "Cloud" toggle,
which behind the scenes edits `server.json` and then restarts the
server.

* gate cloud models across TUI and launch flows when cloud is disabled

Block cloud models from being selected, launched, or written to
integration configs when cloud mode is turned off:

- TUI main menu: open model picker instead of launching with a
  disabled cloud model
- cmd.go: add IsCloudModelDisabled checks for all Selection* paths
- LaunchCmd: filter cloud models from saved Editor configs before
  launch, fall through to picker if none remain
- Editor Run() methods (droid, opencode, openclaw): filter cloud
  models before calling Edit() and persist the cleaned list
- Export SaveIntegration, remove SaveIntegrationModel wrapper that
  was accumulating models instead of replacing them

* rename saveIntegration to SaveIntegration in config.go and tests

* cmd/config: add --model guarding and empty model list fixes

* Update docs/faq.mdx

* Revert "Update internal/cloud/policy.go"

This reverts commit 8bff8615f9b5751fc5c0d1273b07c9de651e07f9.

Since this error shows up in other integrations, we want it to be
prefixed with Ollama

* rename cloud status

* more status renaming

* fix tests that weren't updated after rename
