Rename `AppType` to `AppId` across the entire frontend codebase to better
reflect its purpose as an application identifier rather than a type category.
This aligns frontend naming with backend command parameter conventions.
Changes:
- Rename type `AppType` to `AppId` in src/lib/api/types.ts
- Remove `AppType` export from src/lib/api/index.ts
- Update all component props from `appType` to `appId` (43 files)
- Update all variable names from `appType` to `appId`
- Synchronize documentation (CHANGELOG, refactoring plans)
- Update test files and MSW mocks
BREAKING CHANGE: `AppType` type is no longer exported. Use `AppId` instead.
All component props have been renamed from `appType` to `appId`.
Fixed two critical data loss bugs where user-added custom endpoints were discarded:
1. **AddProviderDialog**: Form submission ignored values.meta from ProviderForm and
re-inferred URLs only from presets/config, causing loss of endpoints added via
speed test modal. Now prioritizes form-collected meta and uses fallback inference
only when custom_endpoints is missing.
2. **ProviderForm**: Edit mode always returned initialData.meta, discarding any
changes made in the speed test modal. Now uses mergeProviderMeta to properly
merge customEndpointsMap with existing meta fields.
Changes:
- Extract mergeProviderMeta utility to handle meta field merging logic
- Preserve other meta fields (e.g., usage_script) during endpoint updates
- Unify new/edit code paths to use consistent meta handling
- Add comprehensive unit tests for meta merging scenarios
- Add integration tests for AddProviderDialog submission flow
Impact:
- Third-party and custom providers can now reliably manage multiple endpoints
- Edit operations correctly reflect user modifications
- No data loss for existing meta fields like usage_script
