calc_dollar_bonus improvements

[nh6574]

Adds calc_dollar_bonus for "individual" objects (by default decks, blinds, challenges, stakes and mods).

For this I added the set and key of the object to its table, which shouldn't break any functionality for any mod adding objects since it is only used if they add a calc_dollar_bonus function to it. Although it could be useful for identifying the objects in the future.

It additionally adds a second table return to the functions that allows some styling manipulation for the name.

• text: sets the text directly
• key, set: changes the key and set for the localization (ignored if text is set)
• text_colour, scale

Additional Info:

• I didn't modify api's or I've made a PR to the wiki repo.
• I didn't modify api's or I've updated lsp definitions.
• I didn't make new lovely files or all new lovely files have appropriate priority.
