Service QoL improvements & assorted changes (#21270)

Does a bunch of stuff relating to service. 

- Adds noticeboards to the bar, kitchen, hydroponics bay, and custodial
closet.
- Adds the microwave meals vendor to the commissary, and expands its
rear maintenance with a crate filled with various bags for all your
retail needs.
- Adds a paper bin to the kitchen.
- Replaces the high power pump feeding the trays in hydroponics with an
enabled regulator, so people don't overflood the pipes thinking higher
pressure is better + so it fills at roundstart. Also replaces all manual
valves with digital valves, so shipbounds can use hydroponics properly.
- Adds better lighting to the public garden so you can grow more stuff
there.
- Fixes a misplaced var with the bar tinted window.
- Makes some assorted layout tweaks to the bar to make the backroom a
more cohesive space, plus adding tinted windows between it and the
cafeteria. This is the most significant change, I'm curious to see if
it'll change much for the bartender to have vision over the cafeteria.
