Unified and reimplemented various banker dialogues

Accessibility to second bank is now locked behind server config toggle second_bank
Eniola, Arnold Lydspor, and Emerald Benedict now offer access to second bank
Locked the backported ability to charge our ring of wealth with GE teleports behind server config toggle ring_of_wealth_teleport
Corrected enchant spells to always yield uncharged dragonstone items, rather than fully charged ones
Fixed inauthentic jewellery UI
Locked the availability of our inauthentic player commands behind server config toggle player_commands. Admins are immune to this and still always have all commands available. Note that this includes ::confirmrules, so be sure not to set your server to show rules and info, but not allow commands
