Add DRATEK eInk integration icons

[dratek-cz]

Proposed change

Add light and dark icons for the DRATEK eInk custom integration (dratek_eink). The integration already ships inline brand assets as required by Home Assistant 2026.3+, but HACS 2.0.5 still reads repository and update-entity icons from the legacy Brands CDN. This submission provides compatibility while the HACS brand proxy changes are pending.

Type of change

• Add a new logo or icon for a new core integration
• Add a missing icon or logo for an existing core integration
• Replace an existing icon or logo with a higher quality version
• Replace an existing icon or logo after a branding change
• Removing an icon or logo

Additional information

• Integration repository: https://github.com/dratek-cz/dratek-eink-homeassistant
• HACS default submission: Adds new integration [dratek-cz/dratek-eink-homeassistant] hacs/default#10778
• HACS repository-icon fix: Add repository brand icon endpoint hacs/integration#5388

Hi there 👋🏻

Thank you for your PR! We really appreciate the contribution.

However, we'll be closing it, as we no longer accept brand icons for custom integrations in this repository. Starting with Home Assistant 2026.3.0, custom integrations can provide their own brand icons directly, so there's no longer a need to add them here.

You can find more details in the announcement:
