Fix shelly tests - bluetooth config flow

[justanotherariel]

Breaking change

Proposed change

Split out from #166683 which tries to fix the flaky tests in the shelly integration. This PR focuses on the bluetooth related tests.

1. Added a new helper _async_inject_ble_discovery (line 62) which now patches the async_init function when calling inject_bluetooth_service_info_bleak which creates a flow otherwise. This is because most tests actually create their own flow manually with hass.config_entries.flow.async_init(DOMAIN, source=BLUETOOTH) which then competes with the Bluetooth Manager's automically created flow. HA detects the duplicate unique ID and aborts one.
2. Replaced most inject_bluetooth_service_info_bleak calls with _async_inject_ble_discovery.

Pull request overview

This PR stabilizes Shelly’s Bluetooth-related config flow tests by preventing the Bluetooth manager from auto-starting competing discovery flows during test BLE advertisement injection.

Changes:

• Added a helper to inject BLE discovery data while suppressing config flow creation during the injection.
• Replaced many direct inject_bluetooth_service_info_bleak calls with the new helper to avoid duplicate/competing flows.
• Switched several tests to use create_mock_rpc_device() so required mock attributes/methods are consistently present.

Cleaning out my review queue. Looks like there are conflicts.

[justanotherariel]

Seems like #168380 already did some of the work that was in this PR. Fixed the merge conflict - should be less to review now.
