Add duration tiers + layered NIP-57 zap verification, extend featured/Pro to tours

- Add 4 duration tiers (7d/30d/90d/365d) with per-day price discrimination to usePlatformFee
- PlatformFeePayment: tier selector UI + attempt NIP-57 zap request (a/p tags), graceful fallback to plain LNURL invoice
- Add getZapProviderPubkey + getZapInvoiceFromLightningAddress helpers
- Add useFeaturedVerification hook (verified/claimed/none) querying kind 9735 zap receipts
- ProBadge: optional entityCoord to show green Verified state on detail pages
- Wire entityCoord through all 5 Become* Lab pages + CoachDetailPage
- Add featuredTour fee type; FeaturedUpgrade generalized for events + tours
- CreateTourPage: featured tag on publish + FeaturedUpgrade UI
- TourCard/TourDetailPage: render ProBadge; sort featured tours first
- Document tiers + zap-receipt verification scheme in NIP.md

+The base is a 30-day monthly price per listing type; the charged amount is
+`base × multiplier`:
+
+| Tier | Days | Multiplier | Note |
+|------|------|-----------|------|
+| 7 days | 7 | 0.4× | short "try it" window |
+| 1 month | 30 | 1.0× | baseline |
+| 3 months | 90 | 2.4× | best value (~20%/day off) |

+
+The chosen tier only determines the computed expiry written into the
+`featured` tag — the tag schema itself is unchanged.
+
+#### Verification via NIP-57 zap receipts (layered / best-effort)
+
+To make Pro tamper-proof where possible, payment is attempted as a **NIP-57
+zap** rather than a plain LNURL-pay. The client signs a kind `9734` zap request
+tagging the platform pubkey (`p`) and, when known, the featured entity's
+addressable coordinate (`a` = `kind:pubkey:d`), and passes it to the platform
+Lightning address's LNURL callback. If the provider is zap-enabled
+(`allowsNostr` + `nostrPubkey`), it publishes a kind `9735` zap receipt.
+
+Clients verify a `featured` listing by querying for a matching kind `9735`
+receipt (`#a` = entity coordinate, `#p` = platform pubkey). Three states result:
+
+| State | Meaning | Badge |
+|-------|---------|-------|
+| `verified` | A matching zap receipt was found. Cryptographically backed. | Green ✓ Pro |
+| `claimed` | Unexpired `featured` tag but no receipt found (provider doesn't publish receipts, or relays lacked it). Self-attested. | Gold Pro |
+| `none` | Not featured / window expired. | (none) |
+
+> **Trust note:** the fallback is **graceful** — if the platform's Lightning
+> provider does not publish zap receipts (as with some custodial/ecash
+> addresses), verification degrades to the older *self-attested* `claimed`
+> level and Pro never silently breaks. When receipts are available the badge
+> becomes genuinely verifiable. For events and tours whose `d` identifier is
+> generated at publish time (non-deterministic), the zap request omits the `a`
+> coordinate, so those fall back to `claimed`.
