fix(setup): retry login up to 3× with 90s timeout and 15s backoff

Hostinger rate-limits GitHub runner IPs on wp-login.php, causing
TimeoutError (30s) during the auth setup step. This has produced 6
deploy-gate failures over 2 days across multiple repos.

Changes:
- Raise navigation timeout from 30s to 90s per attempt
- Wrap the full login sequence in a retry loop (up to 3 attempts)
- Create a fresh BrowserContext per attempt so stale cookies / throttle
  state cannot carry over between retries
- Wait 15s between attempts to let transient throttle windows clear
- Log each attempt number and outcome clearly (console.log + console.error)
  so any future failure is diagnosable from the CI log without a local repro
- On final failure, surface a hint pointing to the Hostinger throttle cause

Assertion behaviour: unchanged. The #wpadminbar check and storageState
write are identical to before — retries only affect getting past wp-login.

No changes to smoke test assertions, playwright.config.ts, or workflow files.

-# Changelog
-
-All notable changes to the peptide-e2e smoke suite will be documented here.
-
-## [1.1.0] - 2026-06-12
-
-### Added
-- **Board page smoke test** (`03-admin-plugins.spec.ts` — `WP Admin — PRAutoBlogger board page`).
-  Navigates to `/wp-admin/admin.php?page=prautoblogger-board`, asserts HTTP 200,
-  `#prab-board` container visible, and body does NOT contain "Invalid plugin page".
-  Guards against the v0.19.1 regression class: Board submenu registered before parent
-  menu existed (both at admin_menu priority 10) → WordPress fallback hookname →
-  wp_die 404. Now in the deploy-gate smoke suite so this failure class is un-shippable.
-
-  Note: cannot be validated against prod until v0.19.1 of PRAutoBlogger deploys.
-  Spec compiles and lists cleanly under `npx playwright test --list`.
-
-## [1.0.0] - 2026-06-11
-
-Initial release. 21 tests across 5 specs: homepage, reconstitution calculator,
-peptide search, admin plugins, REST API.
