NTNet Extensibility (#22908)
Fixes https://github.com/Aurorastation/Aurora.3/issues/21944 Spiritual successor of https://github.com/Aurorastation/Aurora.3/pull/22352 Cherrypicked changes from the C3 Crew Management branch, this PR contains all NTNet extensibility features, including Field Relay construction, off-site camera usage (contingent on standing up remote hardware and being out of jamming), etc. This also fixes a handful of outstanding telecomms and view/mobeye-related bugs adjacent to where I was working. changes: - rscadd: "Adds NTNet extensibility, requires new machinery constructed on away-site z-levels." - rscadd: "Breaks NTNet Relay machinery into Quantum Relay ('core' obj on Horizon) and Field Relay (deployable off-site constructions)." - qol: "Embedded cameras (basically every video camera EXCEPT those which are installed on walls) can now be viewed from NTNet-connected z-level, not just connected ones." - rscadd: "Adds several public camera monitor consoles to the Horizon (near where public sensor grid feed consoles already exist)." - rscadd: "Adds some spare camera console boards to Horizon technical storage." - qol: "Adds action button for 'cancel-camera-view' verb while viewing cameras or looking up/down z-level." - bugfix: "Fixes Jockey comms (frequency was missing from ANTAG_FREQS)." - bugfix: "Fixes look-up/look-down actions intermittently failing without first using cancel-camera-view."
