fix(workflow): include Create Hook LoRA in lora_code_update handler

The validation in getApiEndpoints threw for page types not in
MODEL_TYPES (e.g. 'recipes'), crashing the recipes page initialization
when FilterManager calls it via createBaseModelTags(). The throw was
synchronous and outside the fetch().catch() chain, causing an uncaught
promise rejection that aborted the entire app initialization.

getApiEndpoints is a URL builder -- validation belongs to callers that
need strict type checking (they already use isValidModelType()). For
non-model-type pages like recipes, the generated URLs are correct
(the backend does have /api/lm/recipes/* routes).

Fixes regression from f53f859a (feat(filter): add debounced tag search).
