* fix(ds): goals status filter -> DS::SegmentedControl
The goals status chips were a hand-rolled segmented control: active state
toggled via ad-hoc bg-container/shadow-border-xs/text-* classes, NO hover on
inactive chips, and a light-only focus ring (ring-alpha-black-100, invisible in
dark mode). Migrate to DS::SegmentedControl button segments + toggle the
canonical --active class in goals_filter_controller#syncChipState. Gains the
dark-safe hover (hover:bg-gray-200 / theme-dark:hover:bg-gray-800) and the
canonical focus ring. First control in the tab-consistency pass (#8).
* fix(ds): provider filter chips -> DS::SegmentedControl
Same hand-rolled segmented control as the goals chips: active toggled via
ad-hoc bg-container/shadow/text classes, no inactive hover, light-only
ring-alpha-black-100 focus ring. Migrate to DS::SegmentedControl + toggle the
canonical --active class in providers_filter_controller#syncChipState.
* fix(ds): transaction-type tabs -> DS::SegmentedControl
Expense/Income/Transfer tabs were hand-rolled with a hover==active affordance
bug: inactive hover raised bg to bg-container, identical to the active state, so
hover and selected were indistinguishable. Migrate to DS::SegmentedControl (link
segments + icons); the controller toggles the canonical --active class instead
of swapping ad-hoc ACTIVE/INACTIVE class lists. The client-side nature switch
(expense<->income updates the form's hidden nature field without navigating) is
preserved -- verified live: switching to Income flips the active segment AND
sets the nature field to inflow.
* fix(ds): reports period tabs -> DS::SegmentedControl
The Monthly/Quarterly/YTD/Last-6-Months/Custom period selector was five
DS::Link ghost/secondary buttons -- a different tab idiom than the rest of the
app. Migrate to DS::SegmentedControl link segments (server-rendered active via
aria-current; pure navigation, no controller). Now matches the goals / provider /
transaction-type controls + the AI provider picker. Also autocorrected a
pre-existing single-quote in the next-period aria-label.
