Feat/deeplink multi endpoints (#597)

* feat(deeplink): support comma-separated multiple endpoints in URL

Allow importing multiple API endpoints via single endpoint parameter.
First URL becomes primary endpoint, rest are added as custom endpoints.

* feat(deeplink): add usage query fields to deeplink generator

Add form fields for usage query configuration in deeplink HTML generator:
- usageEnabled, usageBaseUrl, usageApiKey
- usageScript, usageAutoInterval
- usageAccessToken, usageUserId

* fix(deeplink): auto-infer homepage and improve multi-endpoint display

- Auto-infer homepage from primary endpoint when not provided
- Display multiple endpoints as list in import dialog (primary marked)
- Update deeplink parser in deplink.html to show multi-endpoint info
- Add test for homepage inference from endpoint
- Minor log format fix in live.rs

* fix(deeplink): use primary endpoint for usage script base_url

- Fix usage_script.base_url getting comma-separated string when multiple endpoints
- Add i18n support for primary endpoint label in DeepLinkImportDialog
