profile.schema: add missing actions and commands keys (#10384)

Add missing keys to the schema:
- globalSummon (and args: desktop, monitor, name, dropdownDuration, toggleVisibility)
- quakeMode
- iterateOn
- commands

Also enforces required keys for commands and deprecates "keybindings"

## PR Checklist

## Detailed Description of the Pull Request / Additional comments
There were some other pending keys mentioned on the issue, but I don't think they are pending anymore.
