Closes#2001.
DS::Pill defaulted show_dot: true for both modes, so every status/category
badge got a leading dot by default — redundant with the pill shape + tone +
label already carrying the signal, and noisy in dense lists. More than half
the marker:false callsites were already passing show_dot: false to fight it.
The default is now mode-aware: marker: true keeps the dot (stage markers),
marker: false (badges) is dot-less. An explicit show_dot: still wins.
Only one in-tree callsite relied on the old default without an icon and wants
the dot: settings/providers/_status_pill (live connection state) — pinned with
show_dot: true. The enable_banking "Beta" badge loses its dot, which is the
desired outcome (ref #1997). Icon-bearing transaction badges are unaffected
(an icon already suppresses the dot).
Left the now-redundant show_dot: false overrides in place to avoid churn and
conflicts with in-flight pill-migration branches; they're harmless (explicit
false == new default).
Adds tests pinning the per-mode default resolution; updates the Lookbook
preview to show the opt-in dot vs the clean default.
