fix(ui): close consistency-audit contrast and duplication findings

Today hero's top-signal delta used opacity-on-muted text, landing below
AA on the app's most prominent card; five mood charts and the sleep-
stage IN_BED fill painted raw --dracula-*/hardcoded-hex hues with no
(or an unused) light-theme counterpart. Route all of them through
existing semantic/chart tokens instead (destructive/warning/success,
chart-1..5, and a newly minted --chart-inbed with its own Alucard
override) so every hue is AA-tuned per theme.

Also collapses three duplicated primitives the audit flagged: the
click-Popover VitalsInfoTip and hover-Tooltip InfoHint merge into one
touch-first ui/info-popover; MedicationViewToggle and ModuleViewToggle
were verbatim copy-paste and now wrap one shared ui/view-toggle; the
triplicated sport-icon map (already drifted — mixedCardio rendered a
different glyph in the list vs the detail/dashboard views) moves to
lib/workouts/sport-icons.ts with HeartPulse as the settled icon.

Adds a no-restricted-imports lint rule banning direct recharts imports
outside the chart-runtime barrel, catching the bundle-duplication
mistake at local lint instead of PR-CI.
