fix: remove head -5 truncation from UAT file listing in verify-work (#2172)

Projects with more than 5 phases had active UAT sessions silently
dropped from the verify-work listing. Only the first 5 *-UAT.md files
were shown, causing /gsd-verify-work to report incomplete results.

Remove the | head -5 pipe so all UAT files are listed regardless of
phase count.

Closes #2171
