Add combined Presence binary sensor

[bharvey88]

Summary

• Adds a template binary sensor named `Presence` with `device_class: occupancy`
• Combines LD2450 and LD2412 presence detection via OR logic — if either radar detects someone, the sensor is `on`
• Provides a single clean presence entity to use in automations and dashboards

Test plan

• Flash firmware and confirm `Presence` entity appears in HA under the device
• Verify sensor turns `on` when either LD2450 or LD2412 detects presence
• Verify sensor turns `off` when both radars report no presence

Summary by CodeRabbit

• New Features
  • Added a new combined Presence sensor that consolidates occupancy detection from multiple presence sources into a single unified indicator.

Walkthrough

A new template binary_sensor called Presence (id: combined_presence) was added to the ESPHome configuration. It uses device_class: occupancy and returns the logical OR of ld2450_presence and ld2412_presence to provide a unified occupancy signal.

Poem

🐇 I stitched two beacons into one bright tune,

When either wakes, I sing beneath the moon,
One hop, one beep, then both lights gleam,
A cozy signal, soft as cream,
Together they guard the quiet room,
I nibble joy — new presence blooms.

In `@Integrations/ESPHome/Core.yaml`:
- Around line 388-394: The new template binary_sensor "Presence" (id:
combined_presence) just adds an aggregate but does not suppress the original
sources, so Home Assistant will still log id(ld2450_presence) and
id(ld2412_presence); update the earlier definitions of ld2450_presence and
ld2412_presence to be internal/hidden (or set their internal: true / hidden:
true / restore: false as appropriate for ESPHome) or disable their Home
Assistant exposure so only combined_presence is exposed to HA and the logbook
noise is eliminated. Ensure you modify the existing binary_sensor declarations
for ld2450_presence and ld2412_presence (not the new combined_presence block) to
add the chosen hide/internal flag so those sensors stop emitting state changes
to Home Assistant.
