LoginForm: restore proper <label> elements + update e2e tests to the single-step flow

The local-mode LoginForm had drifted to using styled <div> elements as
labels. That's an a11y regression — screen readers can't associate the
label text with the input, and it broke every e2e sign-in helper because
playwright's getByLabel needs a real <label htmlFor="…"> (or aria-label)
association. Restore proper <label htmlFor="email"|"password"> with
matching id="…" on the inputs; keeps the current design comp untouched.

The tests were also written for an OLDER two-step flow — enter email →
click "Continue with work email" → enter password → click "Sign in".
The current form is single-step (both fields, one Sign in click). Update
the shared signIn helper in every spec (p0-p8 + visual) to match, and
switch the label selector to "Email address" so it matches the newly
restored <label> text. Drop the stale a11y assertion in p6 that expected
the two-step button.

Also refresh the marketing landing check in p0-shell.spec.ts:20-22 —
"agentic systems" was in the H1 in an older copy pass; today's H1 is
"Deploy agents at any scale." Update the selector.

Together this unblocks ~30 of the 32 e2e failures; the remaining handful
are downstream product/test drift that will need per-test attention.
