[Feature] Annual renewal system #283

Overview

Members confirm their CARES registrations annually to maintain active status.

Parent: #276

Phase 2 - Activities

Requirements

• FR8.1: Track last confirmation date per registration
• FR8.2: Prompt members to confirm at start of calendar year
• FR8.3: Unconfirmed registrations marked as "lapsed" (not deleted)
• FR8.4: Consecutive confirmations earn longevity recognition

Logic

• Registration is "active" if cares_last_confirmed is within current calendar year
• Unconfirmed registrations become "lapsed" but data is retained
• Longevity seals count consecutive confirmed years
• 2+ consecutive years = longevity recognition

UX

• Dashboard notification for registrations needing confirmation
• Bulk "confirm all" option
• Individual confirmation per species
• Visual distinction for lapsed vs active registrations

Acceptance Criteria

• Annual confirmation prompt appears for registered species
• Confirmation updates cares_last_confirmed date
• Lapsed registrations are visually distinguished
• Longevity indicator shows for 2+ consecutive years
• Bulk confirmation option available
