v1.3.0 ESPHome BLE Keyboard

ESPHome BLE Keyboard v1.3.0

A big release focused on the remote, per-host customisation, and much easier
Home Assistant installation.

Firmware + cards. Re-flash your device to get the component changes. The
Lovelace cards can now be installed and updated through HACS (see below).

🎬 Remote controls

• Record button (HID Record 0x00B2) added to the web server remote and the
  Home Assistant remote card.
• The web server remote gained colour keys (F1–F4) and app-launcher
  shortcuts (Explorer, Browser, Email, Calculator, Search), matching what the
  Home Assistant card already offered.
• Every remote button is now a named action, which is what makes per-host
  remapping and hiding (below) possible.

🎛️ Per-host action overrides

• Any named remote action can now be remapped per host slot, from YAML
  (hosts: → actions:) or live in the web UI's new Host Actions card — no
  re-flash needed to change one.
• Every remote button is now a named action, so all of them are remappable
  (D-pad, power, channel, colour keys, app launchers …). Up to 8 overrides per host.
• Example: make Record drive Windows Game Bar on your PC while a TV keeps
  native HID Record.

🙈 Remove remote buttons per host

• Untick the buttons a host doesn't need — they disappear from the remote for
  that host only (the action still works from macros / YAML / HA). Up to 40 per host.
• Optional hidden_buttons text sensor lets the Home Assistant card mirror
  the same per-host hiding.

💾 Backup & Restore

• Download every runtime setting (macros, host actions, layout, mouse
  calibration, hidden buttons, learned hosts, UI prefs) to a JSON file and
  restore it later or onto another board — new buttons next to Host Actions.

📦 HACS support + visual card editors

• The repo is now HACS-installable (custom repository, category Dashboard)
  — one download brings all three cards and keeps them updated.
• All three cards now have a visual editor in the dashboard UI, so you no
  longer need to hand-write YAML. YAML editing still works.

⚠️ Changed behaviour

• OK button now sends keyboard Enter (0x28) instead of HID Menu Pick
  (0x0041). Enter is accepted by far more hosts (fixes OK doing nothing on
  some smart TVs/monitors while the arrows worked). Hosts that need Menu Pick
  can restore it with a per-host override: ok → consumer:0x0041.

🖥️ Web UI improvements

• New Mouse and Cursor Position preset groups; added the missing plain
  left/right/middle-click presets.
• Host-bar layout fixes so a wrapped host button no longer stretches the row,
  and hosts + Forget Host pack onto one line.
• Tooltips with worked examples on the Host Actions inputs.

📖 Docs

• Documented per-host overrides, button removal, backup/restore, the
  text_sensor platform, HACS install, and a "Developing the cards" guide.
• Fixed the Usage Example, which was missing the web_server: block required by
  web_control: true.
