Add NOK pricing catalog, credit ledger, success-based charging, and tier-gated model routing

- PricingCatalog.php: single source of truth for plans (free/plus/pro), top-ups,
  Stripe price env keys, tool costs (0–6 credits), STT variable billing, feature limits
- FreeTier.php: monthly-first credit deduction, ledger (user_tool_credit_ledger),
  STT reservation/settle/release, monthly reset, trial logic
- StripeClient.php: canonical SKUs (plus/pro/topup_100/300/1000), legacy aliases kept
- stripe-checkout.php: subscription vs payment mode, trial gating, catalog metadata
- stripe-webhook.php: idempotent via stripe_events, handles subscription lifecycle +
  invoice.paid renewal + one-time topup credit grants
- All API tools: success-based credit deduction (check before, charge after)
- transcribe.php: file-size heuristic reservation, settle from actual provider duration
- ask.php + LegalTools.php: ToolModels engine resolution — Pro gets gpt-4o
- KorrespondAgent.php + korrespond.php: tier-gated draft deployment —
  Free/Plus gets gpt-4o-mini, Pro gets gpt-4o
- pricing.php: NOK-only, plan cards, top-up packs, Organisation contact card,
  tool cost table, separate monthly/prepaid balance display
- 003_pricing_credit_catalog.sql: ledger and STT reservation tables

/**
* Credit + tier system for users of tools.dobetternorge.no.
* Credit + tier system for SSO users of tools.dobetternorge.no.
*
* Three tiers: free, plus, pro (NOK pricing, see pricing.php).
*
* Tables:
* user_tool_credits — balance (monthly, resets), bonus_balance (never expires), tier,
* Stripe links, trial_started_at / trial_expires_at / trial_downgraded_at
* user_tool_usage_log — every tool call with credits_used
* user_subscriptions — Stripe subscription ledger
*
* Effective balance = balance + bonus_balance.
* Spend order: deduct from balance first, overflow to bonus_balance.
* Pro tier has the largest monthly allowance (still subject to hourly cap).
*
* Trial is Stripe-driven: when subscription.status='trialing', tier='plus' and
* trial_expires_at mirrors Stripe's trial_end. No homegrown trial cron — the
* Stripe webhook flips tier='free' on subscription.deleted.
*
* CaveauAI client sessions bypass all credit checks.
* Only SSO sessions are subject to limits.
* balance = monthly credits, reset/refilled by tier.
* bonus_balance = prepaid/top-up credits, never expires.
* Spend order: monthly first, prepaid second.
