- Sync all: replace the hand-rolled `button_to` with `DS::Link.new(variant: "outline", method: :post)` — same component as the
"Identify Patterns" button on the recurring-transactions page.
- Search input: switch to the icon-overlay pattern used by the
Manage-currencies and transaction filter rows
(relative wrapper + absolutely positioned search icon +
bordered input with `focus:ring-gray-500`). Brings the keyboard
focus state in line with the rest of the app's filterable lists.
- SnapTrade panel: restore the "needs registration" status row that
the drawer-cleanup pass dropped along with the redundant
Configured/Not configured footer. The unregistered case is
meaningful state, not redundant chrome.
- Move the slim health-strip computation out of the controller and
into `SettingsHelper#provider_health_strip` (Convention 2: skinny
controllers).
- Extract `concise_time_ago` helper so the "drop leading 'about '"
trick stops being duplicated 3x.
- `Settings::ProviderCard#maturity_label` (instance) now delegates
to `.maturity_label` (class) instead of duplicating the lookup.
- Drop unused `warn_or_err` local in `_connection_row`.
- Replace the `data-controller` string-injection + html_safe in
`_connection_row` with `tag.details(data: ...)`; safer and more
idiomatic.
- Add a system test for the empty-filter message wiring.
