feat(tags): add dual tagging system with tag rendering in record details

Description:
Implemented a dual tagging system across the Corpus Client App upload flow and record details pages. Added support for username tags and normal tags using #, integrated backend username search autocomplete, clickable tag navigation, tag detail pages, and rendering of tags inside uploaded record metadata. Tags now persist across uploads and display consistently in record details and profile uploads.
