[wifi_info] Add IP address text sensor

[bharvey88]

Version: 25.8.12.1

What does this implement/fix?

Adds the device's IP address as a diagnostic text sensor using the built-in ESPHome wifi_info platform. The sensor publishes the IP immediately on WiFi connect and updates if it changes — no polling required. It appears in Home Assistant under the device's diagnostic entities, making local access and debugging easier without needing to check the router.

In `@Integrations/ESPHome/Core.yaml`:
- Around line 716-720: Add entity_category: "diagnostic" to the ip_address
sensor under the wifi_info platform so it is placed under the device's
diagnostic entities; locate the wifi_info platform block and the ip_address
sub-key (id: wifi_ip) and add the entity_category property (matching the
wifi_signal_db diagnostic pattern) and optionally add an icon line to match
other diagnostic sensors in this file.
