Add Global Caché iTach IP2IR integration

[orandasoft]

Proposed change

Adds a new Home Assistant integration for the Global Caché iTach IP2IR network infrared controller.

Features include:

• infrared entities for each IR enabled port
• Config flow support
• HA DHCP discovery / GC UDP discovery
• Automatic rediscovery and IP update handling
• Optional remote entity support
• Support for raw timings, Pronto Hex, and named IR commands
• Diagnostics support
• Repairs support
• Full test coverage

When adding new integrations, limit included platforms to a single platform. Please reduce this PR to a single platform. See the review process for more details.

This PR includes a brand folder inside the component. Brand assets should not be part of the core repository. Please refer to the brand images documentation for the correct approach.

Note

Copilot was unable to run its full agentic suite in this review.

Introduces a new Home Assistant integration for Global Caché iTach IP2IR, including discovery, config/options flows, infrared/remote entities, diagnostics, repairs, and a bundled pyitach protocol layer.

Changes:

• Added the itachip2ir integration (config flow, discovery, infrared + remote platforms, options flow, diagnostics, repairs, translations, docs).
• Added a comprehensive test suite for the integration (setup/unload, discovery, infrared, remote, diagnostics, repairs, compat).
• Updated generated registries (integrations, DHCP, config flows), CODEOWNERS, and requirements pins.

Comments suppressed due to low confidence (2)

requirements_all.txt:1

• This introduces two conflicting pins for the same distribution (infrared-protocols) in the same requirements set. Dependency resolution will fail or be non-deterministic. The integration should either align with the existing pinned version (3.5.0 here) or avoid adding a second pin and rely on the already-present dependency.
  tests/components/itachip2ir/conftest.py:1
• This path manipulation appears incorrect: parents[1] from tests/components/itachip2ir/conftest.py points to tests/components, not the repository root, and root / \"homeassistant.components\" is unlikely to exist. This adds potentially misleading entries to sys.path. Prefer removing this fixture entirely (since HA tests already import homeassistant), or compute the actual repo root (e.g., parents[3]) and use the real package path (root / \"homeassistant\" / \"components\") if you truly need it.
