Clear PDA now has all themes (#76674)

## About The Pull Request

Gives all themes to clear PDAs

## Why It's Good For The Game

Clear PDAs are found/purchased late into a round and theme apps would
generally already be found and installed in PDAs. This means there's
nothing left to install in the crystal PDA, so instead I thought why
shouldn't they just get all themes?

## Changelog

🆑
qol: Clear PDAs now has all themes in their themify app by default.
