Activity logging and quote sending modals implemented:
- LogActivityModal: Fast form (<10 sec) for registering calls, emails, meetings, notes
- SendQuoteModal: Two tabs for assigning existing quotes or creating new ones
- FollowUpWidget: Dashboard card showing leads needing follow-up (>7 days no contact)
- Server actions validate and update lead status to 'proposal_sent' on quote assignment
All requirements met (CRM-04, CRM-05, CRM-06, CRM-07). Build passes with 0 errors.
