e2e(FR-2465): review and rewrite failing session E2E tests

[ironAiken2]

Resolves #6416 (FR-2465)

Summary

Session E2E tests were failing due to environment version mismatches and code issues. This PR fixes the root causes:

• TOML duplicate key error (test-util.ts): The test server's config.toml contains debug = true twice under [general]. Added a deduplicateTomlKeys() pre-processor to strip duplicate keys before passing to @iarna/toml parser, which is strict about duplicates.

• Feature flag timing (session-scheduling-history-modal.spec.ts): page.evaluate() to set backendaiclient._features['session-scheduling-history'] was called before backendaiclient was ready. Fixed by adding waitForFunction to confirm client readiness post-navigation before evaluating.

• selectDatetimeProperty scope bug (session-scheduling-history-modal.spec.ts): The helper referenced page from a closure that was not in scope at the describe block level. Fixed by adding page: Page as an explicit parameter and updating all 6 call sites.

• Version-aware datetime filter tests (session-scheduling-history-modal.spec.ts): Created At / Updated At filter options require feat/FR-2302 (added after WebUI v26.3.0). Tests now skip gracefully with explanatory messages when running against an older server build.

• Version-aware cluster mode warning tests (session-cluster-mode.spec.ts): The "Multi-node with size 1" warning requires ClusterModeFormItems.tsx from feat/FR-2381 (not in v26.3.0). Added version-aware skip logic to 3 tests.

• Dependency tests requiring running agents (session-dependency.spec.ts): Tests that create sessions and wait for RUNNING state cannot pass on the test server (no available agents). Marked with test.fixme with explanatory message.

• Coverage report update (E2E_COVERAGE_REPORT.md): Updated test status to reflect current fixme/skip state.

Test plan

• e2e/utils/test-util.ts - deduplicateTomlKeys() handles the config.toml duplicate key issue
• e2e/session/session-scheduling-history-modal.spec.ts - selectDatetimeProperty(page, modal, name) signature is correct; datetime tests skip gracefully on v26.3.0 server
• e2e/session/session-cluster-mode.spec.ts - cluster mode warning tests skip gracefully when FR-2381 feature unavailable
• e2e/session/session-dependency.spec.ts - tests requiring RUNNING sessions are properly marked fixme

Pull request overview

This PR stabilizes Session-related Playwright E2E tests in Backend.AI WebUI by addressing strict TOML parsing failures, fixing test runtime ordering issues, and making tests resilient to feature/version differences across server/WebUI builds.

Changes:

• Added a TOML pre-processor to tolerate duplicate keys when fetching/parsing config.toml in E2E utilities.
• Updated Session E2E specs to (a) wait for backendaiclient readiness before toggling feature flags, and (b) skip tests gracefully when features are unavailable on older builds.
• Marked dependency tests as fixme where the CI/test server cannot satisfy prerequisites, and updated the E2E coverage report accordingly.

Addressed feedback from @agatha197: Fixed the session-template-modal.spec.ts test failure. Replaced the page.waitForURL(/\/session(?!\/start)/) (which timed out at 30s) with the proven pattern from session-creation.spec.ts — waiting for the session row to be visible (60s timeout). This implicitly confirms both navigation and pushSessionHistory completion without relying on URL pattern matching.
