add Basic tier, monthly/yearly billing, and supplier detail redesign

- New Basic tier (€39/mo or €349/yr): verified directory listing with
  enquiry form, contact sidebar, services checklist, social links, no leads
- Monthly + yearly billing for all paid tiers; yearly defaults selected
  in signup wizard with CSS-only price toggle (no JS state)
- Redesigned supplier_detail.html: navy hero with court-grid pattern,
  two-column body+sidebar for Basic+, tier-adaptive CTA strips
- Supplier enquiry form: HTMX-powered, rate-limited 5/24h, email relayed
  via worker task; supplier_enquiries table tracks all submissions
- New supplier columns: services_offered, contact_role, linkedin_url,
  instagram_url, youtube_url (migration 0012)
- _lead_tier_required decorator restricts lead feed to growth/pro;
  Basic users see overview + listing tabs only
- Admin: basic tier in dropdown, new fields in form/detail + enquiry count
- setup_paddle.py: adds 4 new products with yearly interval support
- Webhook handler strips _monthly/_yearly suffixes, Basic gets 0 credits
  and is_verified=1; existing growth/pro webhooks unchanged
- Sort order: pro > growth > basic > free
- 572 tests pass (+2 new for basic tier + yearly webhook variants)

+
+### Fixed
+- **Supplier detail page: locked quote CTA** — "Request Quote" button is now
+  visually disabled (greyed-out) for unverified/free-tier suppliers; clicking
+  opens an inline popover explaining the limitation and linking to the general
+  quote wizard instead
+- **Supplier signup Paddle checkout** — form now intercepts submit, fetches
+  checkout config via JS, and opens `Paddle.Checkout.open()` overlay instead
+  of displaying raw JSON in the browser
+- **Credit balance OOB updates** — sidebar and lead feed header credits now
+  update instantly via HTMX OOB swaps after unlocking a lead (no page refresh)
+- **Boosts page layout** — capped main content column at 720px on wide screens;
+  credit card grid uses `auto-fill` for graceful responsive adaptation
+
+### Added

+  website) trigger HTMX `hx-get` with 500ms debounce to update the directory
+  card preview in real time; new `/dashboard/listing/preview` endpoint and
+  extracted `dashboard_listing_preview.html` partial
+- **Lead cards: full qualification data** — unlocked cards now show decision
+  process, prior supplier contact, financing help preference, with clear
+  section headers (Project, Location & Timeline, Readiness, Contact) and
+  human-readable enum labels; includes "View their plan" link to linked scenario
+- **Lead feed search bar** — text input with 300ms debounced HTMX filtering on
+  country, facility type, and additional info; mirrors directory search pattern
+- **Phone number mandatory in quote form** — step 9 now requires phone with
+  HTML `required` attribute and server-side validation
+- **Supplier-aware dashboard redirect** — `/dashboard/` checks if user has a
+  claimed supplier with paid tier and redirects to supplier dashboard
+- **Inline SVG logo** — replaced PNG logo with inline SVG padel racket icon +
+  Bricolage Grotesque wordmark in navbar and footer
+
+### Changed

+  with Commit Mono for numeric values, added Bricolage Grotesque for planner
+  header and wizard step titles; loaded Commit Mono via fontsource CDN
 - **Migration system: single source of truth** — eliminated dual-maintenance
   of `schema.sql` + versioned migrations; all databases (fresh and existing)
   now replay migrations in order starting from `0000_initial_schema.py`;
