Merge TC_SU_2_7 into TC_SU_2_2 for single run and update.

[jtrejoespinoza-grid]

Summary

This PR contains the changes to merge the TestCase TC_SU_2_7.py into TC_SU_2_2. py

New step order:

Implement this new step sequence in TC_SU_2_2.py (replacing its current 0-6 steps and folding in 2.7's steps). For each step, wire up both the attribute-based verification already in TC_SU_2_2 (where applicable) and the StateTransition/other event verification from TC_SU_2_7, using EventSubscriptionHandler alongside the existing AttributeSubscriptionHandler pattern already used in the file (see Step 4's dual-track pattern as precedent).

New Step	Previous Test Case / Step Reference	Action	Verification
0	TC-SU-2.2 Step 0, TC-SU-2.7 Step 0	Commission the DUT (Requestor) with the TH/OTA-P (Provider).	—
1	TC-SU-2.2 Step 1	DUT sends QueryImage. TH/OTA-P responds Busy, DelayedActionTime=60s.	DUT does not re-query before 120s (existing 2.2 logic).
2	TC-SU-2.2 Step 2 , TC-SU-2.7 Step 2	DUT sends QueryImage. TH/OTA-P responds NotAvailable.	DUT does not re-query before 120s (existing 2.2 logic, unchanged). ADD: StateTransition Querying→DelayedOnQuery with reason kDelayByProvider (from 2.7 step 2).
3	TC-SU-2.2 Step 3	DUT sends QueryImage, Busy/180s, then on retry UpdateAvailable.	DUT waits ≥180s before re-query (existing 2.2 logic). Transfer starts (existing). Do NOT abort immediately — hand off into step 4 instead of killing here.
4	TC-SU-2.2 Step 3 (abort portion), TC-SU-2.7 Step 6	Once kDownloading is confirmed (continuing from step 3's transfer), kill the provider mid-download to force an error (this replaces 2.2's abrupt "kill right after kDownloading" — same kill, but now verified).	StateTransition Downloading→Idle, and this transition must take ≥300s (5 min BDX idle timeout) — from 2.7 step 6. DownloadError event with SoftwareVersion matching, BytesDownloaded>0, ProgressPercent>0, PlatformCode=NULL.
5	TC-SU-2.2 Step 4	DUT sends QueryImage. TH/OTA-P responds UpdateAvailable with an invalid BDX ImageURI.	No transfer starts (existing 2.2 step 4 logic, unchanged).
6	TC-SU-2.7 Step 3	DUT sends QueryImage. TH/OTA-P does not respond (provider killed before announce).	StateTransition Querying→Idle with reason kFailure (from 2.7 step 3).
7	TC-SU-2.7 Step 4	If BasicInformation.LocalConfigDisabled is supported, write it to False via attribute_guard/write_single_attribute (from 2.7 step 4).	—
8	TC-SU-2.7 Step 5	DUT sends QueryImage with RequestorCanConsent=True; provider responds UserConsentNeeded=True (needs --userConsentNeeded + app pipes, from 2.7 step 5).	StateTransition Querying→DelayedOnUserConsent.
9	TC-SU-2.2 Step 5, TC-SU-2.7 Step 1, TC-SU-2.7 Step 7	The single full OTA. UpdateAvailable → DUT downloads V2 → provider sends ApplyUpdateResponse Action=AwaitNextAction (--applyUpdateAction awaitNextAction --delayedApplyActionTimeSec N) → after asserting DelayedOnApply, restart/reconfigure the provider to permit Proceed so the DUT's scheduled retry completes the apply → DUT reboots on V2.	Full StateTransition sequence Querying→Downloading→Applying→Idle (2.2 existing + 2.7 step 1's event checks). StateTransition Applying→DelayedOnApply with reason kDelayByProvider (2.7 step 7). VersionApplied event with correct SoftwareVersion and non-null ProductID (2.7 step 1). Existing 2.2 basic-information version check after reboot.
10	TC-SU-2.2 Step 6	DUT sends QueryImage; provider serves the same V2 version.	No transfer starts (existing 2.2 step 6, unchanged — reuses the already-applied V2 image).

This order consider the old version of 2.7: Not single ota update order (https://github.com/jtrejoespinoza-grid/connectedhomeip/blob/a50d879769df0c0fd984a3545954438ba025813a/src/python_testing/TC_SU_2_7.py)
