Phase 2 Task 29 — public Talk-to-Sales submission endpoint.
- New POST /api/v1/sales-leads (public, no auth, rate-limited 5/hour per IP).
- Inserts a sales_leads row, fires best-effort notification email and
PostHog server-side capture; failures are logged but never fail the
request.
- New EmailService.send_sales_lead_notification static method.
- New SALES_LEAD_RECIPIENT_EMAIL setting (defaults to sales@resolutionflow.com).
- Schemas: SalesLeadCreate / SalesLeadCreateResponse with literal source enum.
- Tests: happy path (row + email), email-failure resilience, and rate-limit
enforcement (re-enables the slowapi limiter for the rate-limit assertion
since DEBUG=true disables it by default in tests).
PostHog server-side instrumentation point is wired in but no-ops gracefully
until app.core.analytics.posthog exists — turning it on is a one-line
change when the backend SDK is configured.
