[utilities/powerplant] src: Fix Birthdate handling, and added birthday icon

Git commit 41a52fe9fbcb9851cbe3155011016b52edac6094 by Carl Schwan, on behalf of Michael Rostom.
Committed on 06/08/2026 at 09:09.
Pushed by carlschwan into branch 'master'.

Fix Birthdate handling, and added birthday icon

* Setting the `Value` for the `FormDateTimeDelegate` instead of `initialValue`. This makes the plant's birthdate show up when editing the page rather than the default "Today"
* Fixed birthdate handling. Because it was saved as a date object instead of dateTime, the date would be off by 1 day sometimes as it gets converted.
* Added cake icon in top left when it is the plant's birthday
