test(web): query credential coverage actions by name

[lyzno1]

Summary

• Replace the remaining concurrent and additional-coverage credential action entry locators with role-and-name queries.
• Remove hidden-button traversal, SVG inspection, and conditional fallbacks that allowed coverage tests to skip the intended action.
• Delete one outside-click test that was proven to be a no-op because its overlay selector never matched the rendered dialog.

Behavior contract

• Delete coverage explicitly selects Delete for concurrency, confirmation reset, Escape close, and credential-id flows.
• Rename concurrency coverage explicitly selects Rename before driving the existing textbox and Save behavior.
• Edit/remove and modal-reset coverage explicitly selects Edit before using the existing textual modal actions.
• This PR depends on test(web): query core credential actions by name #40266 because both layers intentionally simplify the same large owner spec in reviewable stages; test(web): query core credential actions by name #40266 in turn depends on the production names from fix(web): name plugin credential actions #40265.

Visual regression

This is a test-only PR. It has no production bundle, DOM, CSS, layout, interaction, or runtime visual effect.

Validation

• pnpm exec vp check app/components/plugins/plugin-auth/authorized/tests/index.spec.tsx (0 errors, 0 warnings)
• pnpm exec vp test run app/components/plugins/plugin-auth/authorized/tests/index.spec.tsx (61/61)
• pnpm check (0 errors, 2059 existing warnings)
• No remaining Rename, Edit, or Delete SVG-class locators or hidden-action-button traversal in this spec.

Closing during the test audit. This continues a split cleanup of the same oversized spec without adding a distinct behavior contract, and still leaves substantial duplicated/private-implementation coverage.
