Add conditional to Single Core Fix sample code

[DukeSniper]

Do not stop BLE scanning on disconnect if there are still active API connections, only stop when all connections are lost

Description

Current Example code stops scanning on any API disconnect. If both HA and a logging client connect and the logger disconnects, the scanning stops, even tho HA is still connected.

Walkthrough

The docs example for single-core ESP32 now stops BLE scanning on api.on_client_disconnected only when api.connected is false, preventing unconditional scan stops while the API remains connected.

Changes

Single-core chip example correction

Layer / File(s)	Summary
Single-core chip example configuration fix src/content/docs/components/esp32_ble_tracker.mdx	The esp32_ble_tracker.stop_scan action is now wrapped in an if condition that checks not: api.connected, ensuring the scan is stopped only when the API is truly disconnected rather than unconditionally on client disconnection.

In `@src/content/docs/components/esp32_ble_tracker.mdx`:
- Around line 289-294: Add a leading dash before the if action so it matches the
action list syntax used elsewhere; specifically, change the action entry that
currently starts with "if:" (the block that tests "not: api.connected" and then
runs "esp32_ble_tracker.stop_scan") to be prefixed with "- if:" so the
conditional is treated as an item in the trigger's action list.
