Subject: [PATCH 02/10] fix(e2e): fail closed on named TSIO webhook routing

secret so a missing secret never posts to the shared fallback channel.

Canonicalize run_type MAIN→MASTER when building the TSIO identity name,
and treat desktop-main like desktop-master for webhook/notify selection.

Subject: [PATCH 05/10] revert(e2e): drop mistaken desktop-main / MAIN alias
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Desktop master pushes are Matterwick MASTER → desktop-master only.
Mobile keeps MAIN/MASTER→mobile-main; that does not apply to desktop.

Subject: [PATCH 06/10] ci(e2e): point TSIO uploads/status at staging for #81
 validation

Pin report-upload to main@b5580f4 and enable useStaging so desktop E2E
hits staging-test-io after the staging deploy of the Maestro/Detox ingest fix.

Subject: [PATCH 07/10] fix(e2e): harden MM-T4049 settings chrome on Linux
 after tiling

Skip the flaky settings category click that tears down the Linux
WebContentsView mid-action; open/close via cancelModal like focus tests,
and settle briefly after tiling before interacting.
