Reorganize StoredProcedures into subdirectories

[rmartinsen-ucd]

Split the flat datamart/StoredProcedures/ folder into subdirectories grouped by purpose. HealthChecks/ already follows this pattern; the rest should too.

Proposed structure

StoredProcedures/
├── HealthChecks/    (already exists)
├── Reports/         (app-facing, granted to WalterAppRole)
├── Pipeline/        (called by Fabric/SQL Agent pipelines, granted to WalterPipelineRole)
└── Utilities/       (helpers, logging, validators — granted as needed)

Mapping

Reports/ (granted to WalterAppRole):

• usp_GetAllPositionBudgets.sql
• usp_GetEmployeeAccrualBalances.sql
• usp_GetFacultyDeptPortfolio.sql
• usp_GetFacultyDeptPortfolioElzar.sql
• usp_GetGLPPMReconciliation.sql
• usp_GetGLProjectSummaryElzar.sql
• usp_GetGLTransactionListings.sql
• usp_GetLaborLedgerData.sql
• usp_GetPositionBudgets.sql
• usp_GetPPMProjectSummaryElzar.sql
• usp_GetProjectSummary.sql

Pipeline/ (granted to WalterPipelineRole):

• usp_SwapPositionBudgets.sql

Utilities/ (granted as needed by either role):

• usp_LogProcedureExecution.sql
• usp_ParseProjectIdFilter.sql
• usp_SanitizeInputString.sql
• usp_ValidateAggieEnterpriseProject.sql
• usp_ValidateFinancialDept.sql

Notes

• SDK-style SQL projects (Microsoft.Build.Sql) pick up .sql files via globs; no .sqlproj edits needed
• Subdirectories do not affect the deployed schema — everything still lands in dbo
• Reorganize Script.PostDeployment.sql into matching sections (App grants, Pipeline grants, Utility grants) for consistency
• Do the moves in a single PR using git mv only (no content changes) so git rename detection works and reviewers see "100% renames"
