Door damage fixes (#22975)

I had accidentally made doors unbreakable, except by anti_material
weapons, like the PEAC and ship weapons. This fixes that.

Two PEAC shots will still destroy any normal door.

This is mostly a bugfix, the increase to door armour only compensates
for them being mortal again. PEAC basically ignore armor with their 35AP
and 100+ damage to structures.

Regular weapons weaker than a laser rifle still cannot completely
destroy a door.

It takes an STS ~90 rounds to destroy a blast door.

changes:
- bugfix: "Doors and blast doors can be destroyed again with enough
sustained damage."
  - bugfix: "Fixes doors 'breaking' repeatedly, when hit at 0 health."
- bugfix: "Fixes doors taking damage twice when hit by projectiles. This
also fixes projectiles ignoring a door's armour."
- balance: "Increased the armor values on blast doors and vault doors."
  - rscadd: "Added a brief particle effect when a door is destroyed."
