fix(canvas): add focus-visible to secrets-tab add/clear-search buttons

Both .secrets-tab__add-btn and .secrets-tab__clear-search were missing
:focus-visible rules, violating WCAG 2.4.7 (Focus Visible). Keyboard
users tabbing to these buttons would see no visible focus indicator.

Fix: add :focus-visible { outline: var(--focus-ring); outline-offset:
var(--focus-ring-offset); } to both selectors, consistent with the
existing focus-visible pattern used throughout the settings panel.
