Commission Guidelines Update

Updated⁠commission-guide to include the carrd.co link (which includes ToS among other things).
A TLDR process also included for new patreoners.
Nothing new other than some terminology clarifications (no changes to current comms or anything either).

Of note, for the old timers here:

• Alts have been clarified to "scale based on the amount needed to add/adjust from the base version". It was originally listed as +30USD, which can be confusing.,

• This means Alts are still a +30USD minimum, as it's typically the cost of clothing or accessories being toggled.,

• Exceptions will naturally be made for smaller items (e.g. a single cuff earring will not incur an Alt cost)
