feat: show 'Search in progress' derived status on opportunity card

[nadavosa]

Summary

Display statusMatch on the opportunity card (volunteer section), and reflect the auto-derived opp-active status. This is the opportunity-side mirror of the volunteer profile's opportunity section.

Status design

opportunity.status (shown on opportunity header)

Value	Display	How
opp-new	New / Needs validation	Default
opp-searching	Searching	Manual (coordinator)
opp-active	Active	Auto — ≥1 volunteer active
opp-inactive	Inactive	Manual (coordinator) — see #412 (BE), #87 (SDK)

opportunity.statusMatch (shown in volunteer section of opportunity card)

Value	Display
vol-no-matches	No match
vol-pending-match	Pending match
vol-matched	Matched
vol-past	Past

FE changes needed

1. Add statusMatch to opportunity card volunteer section display (badge/label), similar to how volunteer profile shows opportunity status
2. Use statusMatch from SDK ApiOpportunityGet.statusMatch (available after SDK create volunteer editable profile logic #88)
3. The opp-active status on the opportunity header is now auto-set by BE — no manual trigger needed from FE

Depends on

• BE Missing comments row on Volunteer Profile #413
• SDK create volunteer editable profile logic #88
