feat(base,app,keys): keys of shared spaces, sealed to each member
Step 3 of ADR 0044 (D3, D18, D19). A shared space's data keys are
sealed on a device to each member's public keys; the instance keeps
what devices sealed and never opens it.

- halkyon_keys: the safety code of two accounts' public keys
  (`safetyCode`), 60 digits, the same on both sides.
- halkyon_base: the register hands out accounts' public keys
  (`public-keys-of`, local and remote); the table `shared_space_key`
  and the endpoint `sharedSpaceKeys` (memberKeys, keysNeeded, seal,
  mine). Only the Owner and Editors seal, the first key sealed to a
  member stays, and a member's keys go with their membership. Every
  host's migration creates the table.
- halkyon_app: `ContentCipher` seals a key to another account and
  opens one sealed by another; `SharedKeys` shares a space's key with
  its members, seals keys to newcomers and opens the person's own,
  holding each member to the public keys `KeyPins` pinned on first
  sight (`key_pins.json` in the person's folder), a change refused
  until trusted anew.

Learn takes them into its `Privacy` in step 4.
