Add a date & time source for user confidence (stream is live indicator)

[bhaskarjha-dev]

Feature request:

Add an option to display the current date and time—including the time zone—in the OBS session automation overlays. This helps viewers know the stream is really live and not a past recording.

Details:

• The format and style of the date & time source is to be decided. Options may include a browser-based beautiful clock or a simple text source.
• Users should be able to toggle the date & time display on or off through the Dock or Script UI.
• Make sure the feature supports custom time zones or correctly displays the local system time zone.

Goals:

• Give viewers visual assurance that the session is live.
• Keep the implementation seamless and easy to use, in alignment with sbobs's zero-dependency, simple one-click philosophy.

Acceptance criteria:

• A date & time source can be added to the overlay.
• User can show/hide this source via toggle in the Dock or Script.
• The display clearly includes time zone information (automatic or user-configured).
• Matches overlay style and does not interfere with existing scene elements.
