Guillem Arias Fauste 8e444ff98b feat(design-system): add DS::SearchInput primitive (closes #1715 §3) (#1853)
* feat(design-system): add DS::SearchInput + migrate 2 broken-focus callsites

Resolves #1715 §3.

Two standalone search-field callsites — `/settings/preferences`
currency filter and `/settings/providers` filter row — had a hand-
rolled markup that ended in `focus:ring-gray-500`. That utility has
no backing token in the design system (`ring-gray-500` isn't in
Tailwind's default + Sure doesn't register a gray ring color), so
the input rendered with zero focus indicator on a bordered
bg-container surface. Keyboard users couldn't tell when the field
was focused.

Introduce `DS::SearchInput` — icon-on-left, bordered, token-backed
focus ring matching the DS::Button pattern landing in #1840
(`outline-2 outline-offset-2 outline-gray-900` with the dark-mode
override). API:

  DS::SearchInput.new(
    name: "...",
    placeholder: "...",
    value: ...,
    aria_label: "...",   # defaults to placeholder
    class: "...",         # passed to the wrapper
    **opts                # spread onto the <input>, e.g. data-*
  )

Migrate the two broken callsites. Three other "search" patterns
stay as-is (out of scope for this PR):

- `form.search_field :search` inside `styled_form_with` blocks
  (accounts/show/_activity.html.erb, UI::Account::ActivityFeed) —
  already routes through StyledFormBuilder's form-field CSS.
- Embedded-dropdown search input inside DS::Select, DS::Menu, and
  the splits/category-select panels — uses a different shape
  (no border, no ring) because the parent panel provides the chrome.
- Category dropdown's combobox search input
  (app/views/category/dropdowns/show.html.erb) — has a custom
  `role=combobox` flow and stays intentionally distinct.

* feat(design-system): add embedded variant to DS::SearchInput, migrate 2 more callsites

Adds `variant: :embedded` to `DS::SearchInput` for search inputs that
live *inside* another DS panel (DS::Select dropdown, splits category
filter, future DS::Popover-hosted filters). No own border / no own
focus ring — the parent panel provides the chrome, so adding ring
+ outline competes with its `focus-within` state.

API:

  DS::SearchInput.new(variant: :embedded, placeholder: "...", data: {...})

The `:standalone` default (from the previous commit) stays unchanged
and remains the right choice for top-of-list filter inputs.

Migrated:

- `app/components/DS/select.html.erb` — the in-dropdown search input
  for `DS::Select.new(searchable: true)`. Was the only remaining
  internal raw <input type="search"> markup in the component.

- `app/views/splits/_category_select.html.erb` — split-transaction
  category picker filter. Same shape as DS::Select's search but
  hand-rolled because the picker isn't a vanilla DS::Select.

Three other search patterns stay out of scope (intentionally, per
the previous commit):

- `form.search_field :search` inside `styled_form_with` — uses
  form-field CSS, different visual contract.
- `app/views/category/dropdowns/show.html.erb` — bespoke
  `role="combobox"` flow with `aria-expanded` / `aria-autocomplete`
  semantics that don't belong in this primitive.

* fix(review): mobile font + embedded variant focus-within ring

- DS::SearchInput: switch text-sm -> text-base sm:text-sm on both
  variants so the input keeps its 16px base size on mobile. iOS
  Safari zooms the viewport when a focused input is below 16px,
  which the unconditional text-sm was triggering on the Settings
  Preferences currency search and Settings Bank Sync provider
  search.

- DS::Select (searchable variant) + splits/_category_select:
  add focus-within:ring-4 focus-within:ring-alpha-black-200
  (with theme-dark variant) on the wrapper around the embedded
  search input. The embedded variant intentionally has no own
  focus ring so it inherits chrome from its parent panel — but
  the two current parent panels were not providing one, so
  keyboard focus on the dropdown search box rendered with no
  visible indicator. Ring matches the .form-field token used
  across the design system.

* fix(merge): repair DS::Select search input merge resolution

The previous merge of main left invalid Ruby inside the DS::SearchInput
`data:` hash:

    aria-label="<%= t("helpers.select.search_placeholder") %>"

This is an ERB string assignment masquerading as a hash entry — it does
not parse and would have raised SyntaxError at render. Two follow-ups:

- Drop the `aria-label` entry entirely. `DS::SearchInput` already
  defaults `aria_label` to `placeholder`, and `placeholder` is set
  on the call, so the resulting <input> already carries
  `aria-label="<%= t(...) %>"`.

- Restore the `input->select#syncTabindex` action that main #1848
  added on the embedded search input. It keeps the roving tabindex
  on the listbox in sync as filtered results change. Original PR
  branch had only `list-filter#filter`; reintegrate both with
  explicit `input->` event prefixes for parity with main.
