Build query-backed task tracker default template

Add shared colored tags, native tag/status filters, cursor-paged task and
completion views, estimated-hour aggregates and repeat-after-completion actions.
Keep task views independently renderable and isolate component styling.

Cover immutable fresh-template/additive checks, real PostgreSQL/orch package
actions and query watches, and wide/narrow browser layouts. Accept documented
hyphenated query budget names in the capability lexer.

Template publication/default selection pending installation AWS SSO renewal;
no live workspace data or deployment configuration changed.
