Fix 5 additional issues found in round 2 review

- sp_HealthParser: Add missing N'' prefix on dynamic SQL string (line 435)
- sp_HumanEventsBlockViewer: Fix debug label '#blocking_sh' → '#blocking_xml_sh'
- sp_PerfCheck: GETDATE() → SYSDATETIME() for uptime calculation consistency
- sp_PressureDetector: Rename misleading 'physical_reads' column to 'logical_reads'
  (source was der.logical_reads, not der.reads)
- sp_PressureDetector: Fix SUBSTRING start position 0 → 1 in debug PRINT

All 10 procedures tested on SQL2022.
