Fix Emoji Panel Z-Index (#2421)

## Description: Fix Emoji Panel Hidden Behind Player Info Panel

According to : https://github.com/openfrontio/OpenFrontIO/issues/2367

After my previous Player Info Panel layout fix, the Emoji Panel was
accidentally rendered behind it (see
[comment](https://github.com/openfrontio/OpenFrontIO/pull/2410#issuecomment-3507266463)).

This PR updates EmojiTable.ts to ensure the Emoji Panel displays
correctly in front of the Player Info Panel.

Changes:

Increased z-index values for the Emoji backdrop, content, and close
button above z-[10001].

backdrop: z-[10002]

content: z-[10003]

close button: z-[10004]

Expected outcome:
The Emoji picker (backdrop, content, and close button) now correctly
appears above the Player Panel.
