feat(ui): add shared table controls and multi-select filters

Introduce x-table toolbar/search/filter/sort/loading components and
multi-select deployment history filters with OR within groups and AND
across groups. Add live database/service status for breadcrumbs, shared
variables layout controls, logs viewer toolbar polish, and infrastructure
list filter consistency. Document patterns in UI_REDESIGN.md and cover
with feature tests.
