RC dry-run test fixes: QAN search race + RC CLI version resolution

[travagliad]

Draft / WIP — test-side fixes surfaced by the PMM 3.9.0-rc RC-testing dry-run (pmm3-rc-testing #27, RC_VERSION=3.9.0). Scope: pmm-qa test reliability only — no product code. More commits may follow as remaining lanes finish.

Fixes in this PR

1. QAN search page-object race with debounced search (0b2c040)

codeceptjs-e2e/.../queryAnalytics/queryAnalyticsData.js. QAN Overview search became search-as-you-type (debounced ~300ms) in percona/pmm#5537 (PMM-14848). searchByValue()/click() cleared the field before clicking it, which kicks off an empty-search reload of the Overview panel; the following I.click() races that reload and never reaches actionability → ~40s timeout. Reproduced on dev/3-dev-latest (has the feature); passes on 3.9.0-rc (predates it) — so this will bite the 3.9.1 RC. Affected: PMM-T1061, PMM-T1790, and any @qan spec that searches. Fix: click the loaded grid first, let fillField clear+type, and settle with waitForLoaded().

2. RC CLI version resolved from the server, not the moving v3 VERSION (07c5972)

cli/tests/generic.spec.ts. For a pmm3-rc client the Generic suite resolved the expected version by curl-ing pmm-submodules v3/VERSION, which is bumped to the next dev version (3.9.1) the moment the RC branches — while the RC client reports 3.9.0. Result: all six Generic legs (main CLI integration + Compatibility 3.7.0/3.7.1/3.8.0/3.8.1/3.9.0) failed on pmm-admin --version / summary --version. Fix: resolve from pmm-admin status --json (server_version) for pmm3-rc too, reusing the existing feature-build path, so the reference tracks the artifact under test.

MongoDB-update hypothesis — not supported by the evidence

No recent PSMDB/PBM/mongo version bump in pmm-qa. The only mongo change is #1130 (mongodb version resolver endpoint fix — not a bump). The PMM_PSMDB_PBM_FULL matrix (6.0/7.0/8.0), all GSSAPI/CLI PSMDB legs, and PSMDB provisioning are green. The mongo-flavored reds reduce to one PITR flake (PMM-T2036, passed on docker) and one brand-new dashboard test (PMM-T2262) that needs an artifact screenshot to split product-vs-test.

Still open (intentionally not "fixed" by guessing)

• PMM-T2227 (compat tarball-upgrade assertion) — version-gating logic that depends on intended RC-upgrade behavior (cf. Fix RC compatibility CLI failures with correct version gates #1089); needs a maintainer decision.
• Triage items (PMM-T2262, PMM-T1899, PMM-T2029, PMM-T2263/T2202, @rta) — could be genuine 3.9.0-rc product issues; confirm against a live 3.9.0-rc before writing test changes.

Walkthrough

PMM CLI version detection now handles release candidates and URL-based builds. Tarball upgrades validate the applicable remote version. E2E tests retrieve the PMM Server version and skip selected tests below version 3.10.0.

Changes

Version-aware validation and E2E gating

Layer / File(s)	Summary
CLI version detection and upgrade validation cli/tests/generic.spec.ts	Release candidates and explicit build URLs use the server-reported version. Tarball upgrades require a changed version and conditionally validate the remote VERSION value.
E2E server-version gating e2e_tests/api/server.api.ts, e2e_tests/helpers/apiEndpoints.ts, e2e_tests/helpers/version.helper.ts, e2e_tests/helpers/versionGates.ts, e2e_tests/fixtures/pmmTest.ts	The E2E API retrieves and parses /v1/version. The fixture compares the result with configured minimum versions and skips incompatible PMM-T tests.

Merge Risk: 🟡 Moderate · up to 58f67

The PR updates version-gating behavior, but malformed server version strings can bypass compatibility checks and run tests against unsupported PMM Server versions, creating a concrete correctness risk that should be fixed or explicitly accepted before merge.
