Tests: Replace page-level selectors with locators in e2e specs

[Mamaduka]

What?

PR bulk fixes playwright/prefer-locator ESLint warnings in test/e2e/specs by converting page.click( 'role=…' )-style calls to locator chains, preferring getByRole.

Why?

These are leftovers from the pre-locator Playwright API. Locators auto-wait and retry; page-level selector methods don't.

How?

Mechanical conversion, preserving matching semantics:

Selector	Result
role=button[name="X"i]	getByRole( 'button', { name: 'X' } )
role=button[name="X"] (no i)	getByRole( 'button', { name: 'X', exact: true } )
role=button[name=/X/i]	getByRole( 'button', { name: /X/i } )
role=heading[…][level=3]	getByRole( 'heading', { …, level: 3 } )
a >> b	.getByRole( … ).getByRole( … )
text=X / text="X"	getByText( 'X' ) / getByText( 'X', { exact: true } )
CSS selectors	.locator( … )

Testing Instructions

Tests-only change; relying on CI. npm run lint:js -- test/e2e/specs should report no prefer-locator warnings, down from 217, with all other rule counts unchanged.
