ui(activities): center the tickets-remaining line on detail page

Was left-aligned alone on its row above the owned + buy blocks,
which read as visually orphaned. Adding `justify-center` aligns
it with how the line reads as a status pill — same alignment the
buy CTA below uses.

+## Payment Rails Pattern
+
+Shared primitives for modules that mix Lightning + fiat (and, future,
+cash / internal-wallet) payment rails. Activities is the first
+consumer; restaurant + marketplace will adopt the same primitives as
+their backends gain fiat support.
+
+### Vocabulary (canonical — used in code AND UI labels)
+
+| Term | Meaning | Field |
+|---|---|---|
+| **Price currency** | unit the price is quoted in | `currency` |
+| **Payment method** | the rail used to pay (Lightning / Fiat / Cash / Internal) | `payment_method` |
+| **Fiat currency** | currency the fiat provider settles in | `fiat_currency` |
+| **Also accept fiat** | the user-facing label for the `allow_fiat` toggle | `allow_fiat` |
+
+The bare word `Currency` is **banned** in payment-context UI labels —
+it always carries a `Price` or `Fiat` qualifier. The literal string
+`Pay in fiat` is also banned on buyer-side buttons — each fiat rail
+shows as a button labeled with its provider name (`Stripe`, `PayPal`,
+`Square`, `SEPA`). Only the degenerate "providers unknown" fallback
+shows a generic `Card`.
+
+### Fiat-provider architecture (LNbits today)
+
+Fiat providers are configured **globally** by the LNbits admin
+(`lnbits/settings.py`). Each provider has an optional `allowed_users`
+whitelist; the per-session filtered list is exposed as
+`User.fiat_providers: string[]` on `GET /api/v1/auth` (which the
+webapp already reads as `currentUser.fiat_providers`). Both organizer
+and buyer on the same instance see the same list.
+
+Per-user provider configuration is a deferred backend feature. Until
+then, `useFiatProviders` reads the same `currentUser.fiat_providers`
+for both sides.
+
+### Shared primitives (live in base module)
+
+```
+src/modules/base/
+├── composables/
+│   ├── useFiatProviders.ts      // providers + hasAnyProvider + refresh + providerMeta()
+│   └── usePriceConversion.ts    // convert() + useLivePreview(); 60s cache; null on failure
+└── components/payments/
+    ├── PaymentMethodSelector.vue  // buyer-side rail picker
+    ├── FiatToggleField.vue        // organizer-side toggle + conditional fiat-currency dropdown
+    └── PriceConversionPreview.vue // muted "≈ X.XX USD" line
+```
+
+All three components consume services via DI — never import them
+directly across module boundaries.
+
+### `PaymentMethodSelector` data shape
+
+```ts
+type PaymentRail = 'lightning' | 'fiat' | 'cash' | 'internal' | (string & {})
+
+type PaymentMethod = {
+  id: string                  // unique v-for key, e.g. 'fiat:stripe'
+  rail: PaymentRail           // sent as payment_method
+  provider?: string           // sent as fiat_provider when present
+  label: string               // 'Lightning' | 'Stripe' | 'SEPA' | 'Cash' | …
+  icon: Component             // lucide icon
+  available: boolean          // false ⇒ rendered disabled with tooltip
+  unavailableReason?: string  // tooltip when disabled
+  badge?: string              // optional secondary hint, e.g. '≈ 1000 sats'
+}
+```
+
+Module usage:
+- **Activities** passes `[lightning, ...one entry per organizer provider]`.
+- **Restaurant** (future) passes the subset of
+  `[lightning, cash, internal, ...fiat providers]` enabled by the
+  restaurant's `accepts_*` flags.
+
+### Adding a new fiat provider
+
+1. Backend exposes the provider id in `User.fiat_providers`.
+2. Add the id to `KNOWN_PROVIDERS` in `useFiatProviders.ts` with its
+   display label and icon hint (`'card' | 'bank' | 'wallet'`).
+3. Unknown ids fall back to a `Capitalized` label with a `'card'`
+   icon hint — no code change required just for the buttons to
+   render, only for nice branding.
