test(e2e): heal session scheduling history spec for the Astryx UI

[lablup-octodog]

Resolves #10349

Summary

Rewrote the spec's locators against the current UI. The drawer opens by clicking the mocked session name button. The Status entry is found as a MetadataList term/definition. Filters go through the PowerSearch typeahead ('Search filters'), the Field/Operator/Value editor popover and the Apply button, and are asserted via the token's 'Remove : ...' button. Datetime filters use the 'Open calendar' button and the 'Choose date' grid. The refresh button is now 'Refresh'. The enqueue row is matched by text, and collapse re-clicks the single 'Expand row' toggle. The backdrop-dismiss test became an Escape-dismiss test because SessionSchedulingHistoryModal is variant='fullscreen' since #9048 and has no reachable backdrop.

Root cause

The product works: the history button sits next to the Status badge in SessionDetailContent.tsx:417 with the accessible name 'Session Scheduling History'. The spec still targeted antd-era DOM (tr.ant-table-row, '.ant-space-compact .ant-select', '.ant-picker', '.ant-tag', '.ant-modal-wrap', a 'history'-named button, a Status table row), all gone after the Astryx migration and #9048, so openSessionDetailDrawer timed out before any assertion.

Changes

• e2e/session/session-scheduling-history-modal.spec.ts: replace antd selectors with role-based Astryx/PowerSearch/DataGrid locators, add selectFilterProperty/applyFilterValue/getFilterTokenRemoveButton helpers, parametrize the Created At/Updated At date picker and apply tests, replace backdrop dismissal with Escape dismissal

Draft: related e2e not verified: nightly (https://webui-nightly.lablup.ai/, test-only change): ❌ passed 16 / failed 2. The nightly WebUI (webui-nightly) serves main, so the runner cannot prove the fix there; a reviewer should confirm before marking ready.

Judgment points (please review)

• The 'close by clicking outside (backdrop)' test was replaced with 'close by pressing Escape' because feat(FR-3668): redesign scheduling-history sub-steps as a compact inline table and open the modals full screen #9048 intentionally opens the modal full screen (variant='fullscreen'), leaving no backdrop to click. Alternative: delete the test outright.
• Two tests ('remove an applied filter' and 'remove an applied Created At datetime filter token') still fail on nightly because of product bug Property filter clear-all button overlaps the last filter chip's remove button #10289: in this narrow filter, the Tokenizer end lane (loading spinner + 'Clear all' button) covers a single token's 'Remove' button and intercepts the click. Because the spec is serial, that failure also stops the 16 tests after it; in parallel mode the other 24 tests pass. The fix was left out of this PR because it belongs to Property filter clear-all button overlaps the last filter chip's remove button #10289. Options: land the fix(#10289): keep filter chips clear of the clear-all button #10291 approach (reserve --_tokenizer-end-lane-reserve on the tokenizer wrapper in BAIPowerSearchAdapters.css) first, or drop mode:'serial' from this spec.

Rebased onto main (85448fc4e5, clean). Re-verified the whole spec with --repeat-each 2 --retries 0, against a dev server built from #10407 (the PowerSearch occlusion fix), backend frontend.latest.staging: 48/48 passed.

The two failures in the earlier runner verification came from the filter-chip remove (x) being covered by the clear-all lane (#10289 / #10352). #10407 fixes that.

Marking this ready. Merge it after #10407. Before that fix lands, the chip-remove steps still fail against main.

Nightly draft cleanup.
