fix: add account_tiers and admin_settings tables to payment migrations

- Fixed lost account tiers after server restart
- Fixed lost payment gateway configurations on MySQL
- Added _create_account_tiers_table() method to create tiers table
- Added admin_settings table to _create_config_tables()
- Added default free tier insertion if none exists
- Both fixes use CREATE TABLE IF NOT EXISTS to preserve existing data
- Resolves issues introduced in commits f997a0fb and 0052431f

+# Database Migration Fixes for v0.99.29
+
+## Issues Fixed
+
+### Issue 1: Lost Account Tiers After Server Restart
+
+**Problem**: Custom account tiers disappeared after restarting the server, leaving only the default "Free Tier".
+
+**Root Cause**: 
+- On April 14 (commit `f997a0f`), the `account_tiers` table creation was removed from `database.py` migrations
+- On April 16 (commit `0052431`), payment migrations were added but didn't include `account_tiers` table creation
+- The payment migrations referenced `account_tiers` (via foreign keys) but never created it
+- Result: When migrations ran, the table structure existed but custom tiers were lost
+
+**Fix Applied**:
+- Added `_create_account_tiers_table()` method to `aisbf/payments/migrations.py`
+- Creates the table with all necessary columns including `is_visible`
+- Ensures default "Free Tier" is inserted if no default tier exists
+- Uses `CREATE TABLE IF NOT EXISTS` to preserve existing data
+
+### Issue 2: Lost Payment Gateway Configurations (MySQL)
+
+**Problem**: After upgrading to v0.99.29 on MySQL, payment gateway configurations (Stripe, PayPal, crypto) were lost.
+
+**Root Cause**:
+- Payment gateway settings are stored in the `admin_settings` table
+- The `admin_settings` table was only created in `database.py` migrations (line 3335-3342)
+- It was NOT included in `aisbf/payments/migrations.py`
+- On MySQL installations using payment migrations, the `admin_settings` table was never created
+- Result: Payment gateway settings had nowhere to be stored and were lost
+
+**Fix Applied**:
+- Added `admin_settings` table creation to `_create_config_tables()` in `aisbf/payments/migrations.py`
+- Table stores payment gateway configs, encryption keys, and other admin settings
+- Uses `CREATE TABLE IF NOT EXISTS` to preserve existing data
+
+## Changes Made
+
+### File: `aisbf/payments/migrations.py`
+
+1. **Added `_create_account_tiers_table()` method** (lines 68-92):
+   - Creates `account_tiers` table with all columns
+   - Includes `is_visible` column for tier visibility control
+   - Called first in migration sequence to ensure it exists before other tables
+
+2. **Added `admin_settings` table creation** (lines 318-325):
+   - Added to `_create_config_tables()` method
+   - Stores payment gateway configurations as JSON
+   - Stores encryption keys and other admin settings
+
+3. **Added default tier insertion** (lines 527-557):
+   - Ensures "Free Tier" exists if no default tier is present
+   - Prevents empty tier list after fresh installation
+
+## Migration Safety
+
+Both fixes use `CREATE TABLE IF NOT EXISTS`, which means:
+- ✅ Existing tables are preserved
+- ✅ Existing data is NOT deleted
+- ✅ Safe to run on existing installations
+- ✅ Safe to run multiple times
+
+## What Users Need to Do
+
+### For Lost Tiers (SQLite and MySQL):
+1. Restart your server - the migrations will run automatically
+2. The table structure will be verified/created
+3. **You will need to recreate your custom tiers** through the admin dashboard
+4. Future restarts will preserve your tiers
+
+### For Lost Payment Gateway Configs (MySQL only):
+1. Restart your server - the migrations will run automatically
+2. The `admin_settings` table will be created
+3. **You will need to reconfigure your payment gateways** through the admin dashboard:
+   - Go to Admin → Payment Settings
+   - Configure Stripe, PayPal, and crypto gateways
+   - Save the configuration
+4. Future restarts will preserve your settings
+
+## Prevention
+
+These fixes ensure that:
+- All required tables are created by payment migrations
+- Data is preserved across server restarts
+- Both SQLite and MySQL installations work correctly
+- Payment system tables are self-contained in payment migrations
+
+## Testing
+
+To verify the fix works:
+
+```bash
+# Test migrations
+cd /working/aisbf
+python3 -c "
+from aisbf.database import DatabaseRegistry
+from aisbf.payments.migrations import PaymentMigrations
+
+db = DatabaseRegistry.get_config_database()
+migrations = PaymentMigrations(db)
+migrations.run_migrations()
+print('✅ Migrations completed successfully')
+"
+```
+
+## Version
+
+These fixes are included in v0.99.29 and will be part of the next release.
