Fix AA0237 violations to enable CodeCop rules AA0073 and AA0237 as errors

[Copilot]

Fixes the build failures that block merging PR #7402, which re-enables CodeCop rules AA0073 and AA0237 as Error. All 94 violations were AA0237: record variables named with a Temp prefix but not declared temporary.

Changes

• src/rulesets/CodeCop.ruleset.json: Promote AA0073 and AA0237 from None → Error
• 47 files in src/System Application/App/: Add temporary keyword to 94 record variable declarations that carried the Temp naming prefix without the matching modifier

Example fix

// Before
TempEmailAccounts: Record "Email Account";

// After
TempEmailAccounts: Record "Email Account" temporary;

Affected modules: Email, Security Groups, Performance Profiler, Permission Sets, Agent, SharePoint, Word Templates, MCP, User Settings, Guided Experience, Barcode, Extension Management, AppSource Gallery, Azure AD, and more.
