Show full URL examples with highlighted IDs instead of "Contact Help"

What you want the feature to do: Update the helper text or tooltip on video input fields to show a visual example of a full browser URL, with the specific required Video ID or Code clearly highlighted. Instead of directing users to a help center article or support button when they get confused, show them exactly what to copy right on the page.

• YouTube Example: Show [https://www.youtube.com/watch?v=](https://www.youtube.com/watch?v=)dQw4w9WgXcQ (with the 11-character ID bolded/highlighted).

• Vimeo Example: Show [https://vimeo.com/](https://vimeo.com/)123456789 (with the digits bolded/highlighted).

Why it would help your event experience: When people paste the whole URL into a field that only wants the ID, it's usually because the UI doesn't make it clear what an "ID" actually looks like. Telling them to contact help or read a guide is unnecessary friction for a simple fix. Showing the full URL and highlighting the exact piece they need allows them to fix it themselves instantly, saving everyone time and avoiding minor formatting annoyances.

How other organizers could benefit too: This greatly improves the self-service usability of the platform for both organizers and speakers. It reduces the number of simple formatting mistakes across all events and prevents users from abandoning the page to submit support tickets for something that can be explained in a single visual example.
