feat(judging): unallocated partner funds become a warning, not a blocker (#574)

Mirrors the backend relaxation. The allocator preview's
"Ready to publish" badge previously turned amber whenever any partner
contribution had unallocated balance — but the backend gate that
backed that signal has been relaxed (the funds stay in escrow
post-publish; they're not lost).

Split the existing publish-readiness messaging into two lists:

- Blockers — the hard gates (deadline, completeness, no reviews).
  Same red treatment, same ready-to-publish badge logic.
- Warnings — informational, never blocks. Renders in blue, calls out
  the unallocated amount with a note that it remains in escrow.
