Issue:
Bug: feat(core): Implement UCS based upi for paytm and phonepe



## Feature Request: Implement UPI Intent and QR Code Payment Flows for UCS Integration

### Description
Add support for UPI Intent and QR code payment methods through the Unified Connector Service (UCS) for Paytm and PhonePe payment gateways.

### Background
UPI is a critical payment method in India. Currently, Hyperswitch lacks support for UPI Intent (for mobile apps) and QR code flows through the UCS integration. This limits merchants' ability to accept UPI payments through these popular payment gateways.

### Requirements
- Add default implementations for Paytm and PhonePe connectors
- Support UPI Intent payment method for mobile app integrations
- Support QR code generation and payment flow for UPI
- Route payment requests through UCS (actual payment processing handled by UCS)
- Add necessary configuration entries for both connectors

### Technical Details
- The implementation should follow the existing UCS architecture pattern
- No direct API integration with Paytm/PhonePe required (handled by UCS)
- Need to add routing logic and connector definitions
- Should support standard payment operations: create, sync, refund

### Acceptance Criteria
- Successfully create UPI Intent payments through Paytm and PhonePe via UCS
- QR code generation works for UPI payments
- Payment status sync operations function correctly
- Configuration properly set up across all environments

## Fixed #8734

## Description
<!-- Describe your changes in detail -->

This PR implements UPI Intent and QR code payment flows for the Unified Connector Service (UCS) integration, adding default implementations for Paytm and PhonePe connectors.

### Key Changes:
- **Default Connector Implementations**: Added default implementations for Paytm and PhonePe connectors (the actual payment processing integration is handled by UCS)
- **UPI Intent Flow**: Implemented UPI Intent payment method support for mobile app integrations through UCS
- **QR Code Flow**: Added QR code generation and payment flow support for UPI payments via UCS
- **UCS Enhancement**: Extended the Unified Connector Service to route UPI Intent and QR code payment requests
- **Configuration**: Added necessary configuration entries for both connectors across all environments
- **Testing**: Included test suites for the default implementations

**Note**: This PR does not implement direct integrations with Paytm or PhonePe APIs. The actual payment processing and API communication is handled by the Unified Connector Service (UCS). This PR provides the necessary scaffolding and routing logic to support these payment methods through UCS.

### Additional Changes

- [x] This PR modifies the API contract
- [ ] This PR modifies the database schema
- [x] This PR modifies application configuration/environment variables

## Motivation and Context
<!--
Why is this change required? What problem does it solve?
If it fixes an open issue, please link to the issue here.

If you don't have an issue, we'd recommend starting with one first so the PR
can focus on the implementation (unless it is an obvious bug or documentation fix
that will have little conversation).
-->

This change enables merchants to accept UPI payments through Paytm and PhonePe payment gateways using the Unified Connector Service. UPI is a crucial payment method in India, and supporting Intent and QR code flows allows for seamless integration across mobile apps and web platforms.

The implementation leverages the UCS architecture where:
- Hyperswitch provides the routing and orchestration layer
- UCS handles the actual integration with Paytm and PhonePe APIs
- This PR adds the necessary connector definitions and routing logic to support these payment methods

## How did you test it?
<!--
Did you write an integration/unit/API test to verify the code changes?
Or did you test this change manually (provide relevant screenshots)?
-->

### Automated Tests
- Added integration tests for both Paytm and PhonePe default implementations in `crates/router/tests/connectors/`
- Tests verify:
  - Proper routing of payment requests to UCS
  - UPI Intent payment method handling
  - QR code flow support
  - Status sync operations
  - Refund request routing
  - Webhook handling
- All tests pass successfully with the new implementations

### Manual Testing
1. **Enable UCS configuration:**
```bash
curl --location 'http://localhost:8080/configs/' \
--header 'Content-Type: application/json' \
--header 'api-key: [REDACTED]' \
--header 'x-tenant-id: public' \
--data '{
    "key": "ucs_enabled",
    "value": "true"
}'
```

2. **Create a UPI Intent payment request:**
```bash
curl --location 'http://localhost:8080/payments' \
--header 'Content-Type: application/json' \
--header 'Accept: application/json' \
--header 'api-key: [REDACTED]' \
--data-raw '{

## Checklist
<!-- Put an `x` in the boxes that apply -->

- [x] I formatted the code `cargo +nightly fmt --all`
- [x] I addressed lints thrown by `cargo clippy`
- [x] I reviewed the submitted code
- [x] I added unit tests for my changes where possible


Testing:


### Automated Tests
- Added integration tests for both Paytm and PhonePe default implementations in `crates/router/tests/connectors/`
- Tests verify:
  - Proper routing of payment requests to UCS
  - UPI Intent payment method handling
  - QR code flow support
  - Status sync operations
  - Refund request routing
  - Webhook handling
- All tests pass successfully with the new implementations

### Manual Testing
1. **Enable UCS configuration:**
```bash
curl --location 'http://localhost:8080/configs/' \
--header 'Content-Type: application/json' \
--header 'api-key: [REDACTED]' \
--header 'x-tenant-id: public' \
--data '{
    "key": "ucs_enabled",
    "value": "true"
}'
```

2. **Create a UPI Intent payment request:**
```bash
curl --location 'http://localhost:8080/payments' \
--header 'Content-Type: application/json' \
--header 'Accept: application/json' \
--header 'api-key: [REDACTED]' \
--data-raw '{
