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.
-
-## [1.3.0] - 2026-06-12
-
-### Fixed
-- **Auth setup survives `ERR_ABORTED` on wp-login.php** (`global.setup.ts`).
-  When Hostinger's LiteSpeed throttles a GitHub runner IP, `page.goto` can
-  throw `net::ERR_ABORTED` rather than a `TimeoutError`. Playwright marks the
-  browser context closed internally on abort, so the existing
-  `context.close()` call in the catch block threw
-  `"browserContext.close: Target page, context or browser has been closed"`,
-  which propagated out of catch and killed setup before the remaining retries
-  ran. Two production deploys were blocked by this flake on 2026-06-12.
-
-  Fix: introduced `safeClose()` helper that swallows the already-closed
-  error, so an aborted context never terminates the retry loop. Max attempts
-  raised from 3 → 5; backoff is now exponential (5 s / 10 s / 20 s / 40 s)
-  instead of a flat 15 s, giving the throttle window more time to clear.
-  Worst-case timing: 5 × 90 s navigation + 75 s backoff = ~525 s, well under
-  the 900 s (15 min) job timeout. Final-failure message explicitly names the
-  LiteSpeed throttle hypothesis so future CI logs self-diagnose.
-
-## [1.2.0] - 2026-06-12
-
-### Added
-- **Dossier page smoke test** (`03-admin-plugins.spec.ts` — `WP Admin — PRAutoBlogger Article Dossier`).
-  Navigates to `/wp-admin/admin.php?page=prautoblogger-dossier&post_id=<N>`, asserts HTTP 200,
-  `#prab-dossier` container visible, body does NOT contain "Invalid plugin page" or "Fatal error".
-  Guards against: menu-ordering regression (wrong hookname → wp_die 404), PHP fatals on dossier
-  load, missing dossier container, and stage-section regression.
-
-  Defensive strategy: tries canonical staging post IDs 925/930 first, then falls back to the
-  most recent REST post, then falls back to post_id=0 (graceful empty state). Stage-section
-  assertions are conditional on a run record existing. Loud test.info() annotations on fallback
-  paths. New in PRAutoBlogger v0.19.2 / v0.19.3.
-
-## [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.
