* feat: make medication names clickable in Dashboard dose schedule
Add click handlers to med-name-stack divs in all three dose schedule
sections (past, current/overdue, future) on DashboardPage, opening the
MedDetail modal on click.
Add early-return guards to all four modal openers in AppContext
(openMedDetail, openImageLightbox, openScheduleLightbox, openUserFilter)
to prevent duplicate pushState entries on double-click, which caused
unexpected navigation to the Medications page.
Closes#266
* fix: stabilize dashboard modal and image click handling
* fix: close medication detail on first backdrop click
