feat(studio): clickable install pills + open-in-editor on flow cards (v0.43.0)

When a saved flow is missing modules, each capability pill in the
"Needs:" row is now clickable: tap one and a per-item progress
dialog walks the bare capability name through installModule, then
the flows page refreshes. When more than one capability is missing,
an extra "Install all (N)" button runs the same dialog over the
whole list sequentially so a fresh operator can take an unrunnable
flow and one click later have its dependencies resolved.

Also adds a pencil icon next to Run that hands the YAML path to
the OS via SystemActions.openInOs — the operator's default editor
for .yaml decides what opens. Makes the path next to the flow name
actionable instead of decorative.

The install dialog renders one row per spec with a status icon
(pending circle / spinner / check / error), shows the installed
version on success, and surfaces the full error in a copyable
FaiErrorBox on failure so the operator can paste it back.
