fix: logo crop, navbar alignment, buyer names, tender URLs

- Crop logo image (remove 58% bottom whitespace)
- Logo 90px, centered with nav links
- Cursor fix restored (no I-beam on non-interactive content)
- Contracts Finder: fix empty authority_name (was looking for procurer role, CF uses buyer)
- Contracts Finder: generate notice_url from OCID when release.url is empty
- Find a Tender: fix doubled base URL in notice_url
- Dashboard: use authority_name field (not buyer) for tender cards
- Card shadows strengthened on auth pages
- Password eye icon repositioned inside input
