Persist template filters (#6657)

This pull request adds persistent filter and sort settings to the
template library, allowing users' filter choices and sort preferences to
be saved and restored across sessions. The main changes include
integrating the settings store with the template filtering composable,
updating the schema and core settings, and ensuring filter changes are
saved efficiently.

**Template Library Filter Persistence:**

[`src/composables/useTemplateFiltering.ts`](diffhunk://#diff-a1ec9d65962033526942cbcabeac8538ef3cd723e2e9e889cf668ccf6270d167L1-R32):
The filter state (`selectedModels`, `selectedUseCases`,
`selectedRunsOn`, and `sortBy`) is now initialized from the settings
store and changes are persisted back using debounced watchers. This
ensures user preferences are saved and restored.

Added new hidden settings for template filter selections and sort
preference, with sensible defaults.

[`src/schemas/apiSchema.ts`](diffhunk://#diff-b769532e74f826ca909951c0c34331b9246efb3f6901ff95a856ecf01ad826beR504-R514):
Updated the settings schema to include the new template filter and sort
settings, ensuring type safety and validation.

**Default Behavior Adjustment:**

[`src/composables/useTemplateFiltering.ts`](diffhunk://#diff-a1ec9d65962033526942cbcabeac8538ef3cd723e2e9e889cf668ccf6270d167L200-R209):
Changed the default sort order when clearing filters to `'newest'` to
match the new default in settings.
