<!-- Describe your changes in detail -->
This endpoint allows deleting saved payment methods for a customer
To implement this **search_filter** feature, you'll need to modify these architectural layers:


**1. API Request/Response Models**
   - `crates/api_models/src/payment_methods.rs`

**2. Core Business Logic**
   - `crates/router/src/core/payment_methods.rs`

**3. Type Definitions**
   - `crates/router_env/src/logger/types.rs`

**4. Utils**
   - `crates/router/src/routes/lock_utils.rs`

**5. Other**
   - `api-reference-v2/api-reference/payment-method-session/payment-method-session--delete-a-saved-payment-method.mdx`
   - `api-reference-v2/mint.json`
   - `api-reference-v2/openapi_spec.json`
   - ... and 4 more files

**Code Patterns Applied:**
- Define new data structures (1 changes)
- Implement new functions (4 changes)
- Extend existing types with new fields (17 changes)

**Detailed Identifier Changes:**
