Add tracking for rare garrison / order hall / shipyard missions

[rdw-software]

Only those that a) spawn very infrequently and b) award valuable goods should likely be tracked. Examples: Toys, pets, Elite Strike missions

Roadmap:

• [ ] Compile list of relevant missions, by type
• [ ] Add tracking for the GarrisonUI / mission status APIs
• [ ] Add default tasks for these missions
