Add bot types with a permission matrix, and workspace admin bots

A bot's powers came from bots.kind alone, so only the coordinator could
hand work to other bots. bot_types now works like user_types: a row with
no workspace holds everywhere (the coordinator), one with a workspace
only there (a workspace admin), and no row is a worker. bots.kind stays
the legacy marker of the one coordinator for who sees it.

The matrices in src/dict/bot-types-dict.ts say what each type may do,
whom it may direct and who grants it, read by one generic interpreter
(rbac/type-assignment.ts) that userTypeAssignment now wraps too. Every
run reads its powers once (grabBotRunPowers) and the chat tools, task
runs and task tools gate on them instead of kind; a run's powers are its
type's and its user's together.

In the workspace it leads, an admin hands tasks to the workers there
(results relayed back to it), sets their instructions, adds tasks to
their lists and keeps the workspace's context when its user may. Super
admins and admins grant it from the workspace's settings or the chat
header's menu, and the coordinator with set_bot_type. Admins are marked
with a filled green shield beside their name across the workspace, kept
live by pushBotUpdated's admin_workspace_ids.
