feat(search): add browse text search across local library and novelfire.net

Adds GET /api/search Go endpoint that queries PocketBase books by title/author
substring and fetches novelfire.net /search results via parseBrowsePage(),
merging results with local-first de-duplication. The browse page gains a search
input that navigates to ?q=; results show local vs remote counts and hide
pagination/filter controls while in search mode.
