auto-refresh sidebar panels, pin/focus accordion logic

Decisions: file-change subscription for decisions/*.md plus 1-minute
scheduler tick. Tickets: 1-minute scheduler tick plus changed-event
subscription from status button clicks. PQL markdown tab: file-change
subscription for *.md files. All panels get a manual refresh button.

Accordion sections use pin/focus logic: manually toggled sections are
pinned and stay open; the focused item's section auto-opens; unpinned
sections without focus auto-collapse. Both decisions and tickets views
use ClideAccordion with this pattern.

Ticket sidebar split into six status sections (IN PROGRESS, REVIEW,
READY, BACKLOG, DONE, CANCELLED) matching pql's actual statuses.
Status changes scroll the ticket into its new section.
