[Bug]: File Request: "Enter your name" dialog layout is broken — content cut off or overlapped

[1358]

Steps to reproduce

Nextcloud version: master

1. Go to Files and create a new File Request.
2. Save the file request and copy the generated share link.
3. Open the share link (e.g. in a private/incognito window or a different browser).
4. Observe the "enter your name" dialog — the initial prompt shown to the recipient before they can upload files.

Expected behaviour

The dialog renders at an appropriate size, displaying all text clearly and without overlap or truncation. The overall design communicates its purpose cleanly and professionally.

Actual behaviour

The dialog has several layout and UX issues:

• Dialog too narrow: The title wraps across multiple lines even for moderately long subjects, and the background content bleeds through on the left and right sides, indicating the dialog dimensions are not properly constrained.
• Redundant content: The heading and the info box below it convey essentially the same information, which wastes space and adds visual noise.
• Button label: "Send name" is an unusual label for this action — something like "Continue" or "Confirm" would be more intuitive.

The overall impression is that this dialog has never been tested with real-world data such as longer subjects or special characters.

Additional information

A redesign of this dialog component should at minimum define proper minimum and maximum widths, handle long subjects gracefully, and reconsider the information hierarchy to avoid redundancy.
