Add framed privacy notices to game and player forms

[Adarshkumar0509]

Summary

• Adds a framed privacy notice below the game form.
• Adds a framed privacy notice below the player form.
• Uses the exact wording suggested in the issue discussion.
• Does not change any existing workflows or validation logic.

Notice text
Please note: Avoid submitting sensitive and/or personal information to minimize the risk of data exfiltration due to accidental data exposure.

Scope
This PR intentionally only implements the “warning first” approach discussed in the comments, by adding the framed notices to both forms. It does not yet implement:

• The fixed list of 82 character names
• Random assignment of player names
• Random game names

I’m happy to help with the random name functionality as a follow-up if you’d like and once the design is agreed.

Fixes #1909

Hi, I am unable to see the message.

copi.owasp.org/lib/copi_web/live/player_live/form_component.html.heex

is a former template that isn't used anymore, can you remove it?

Use this instead:

copi.owasp.org\lib\copi_web\live\player_live\form_component.ex

We need a notice as well on the game name input.

Updated to use form_component.ex and removed the old .html.heex template. The framed privacy notice now appears below the player form (and I can add the same for the game form similarly).

The build is failing. I believe you have an issue with the Phoenix template.
