This PR refactors get_pain() to be essentially performance free.

DO_UNIQUE prevented a second person scanning the same patient at the

Fixes health analyzers NOT mounted on hardsuits (handheld, observer) not
displaying TGUI on scan due to casting runtime. Fixes unrelated bug with
self-scanning not playing nice.
Various fixes and cleanups for hardsuits following the rework.
changes:
- bugfix: "Adds additional safety checks to hardsuit deployment logic to
better handle boot checks."
- bugfix: "Hardsuit Health Analyzer module works again."
- rscadd: "Adds 'Retract All Parts' verb for hardsuits."
- rscdel: "Removes Vitals Scanner module; hardsuits which had this
module by default have had it replaced with the Health Analzyer module."
- rscdel: "Removes hardsuit Maneuvering Jets onmob sprites."
