fix: resolve transaction lookup, compliance search injection, dashboa…

[muazumikail1915-create]

Summary

• [Bug] Fix transaction lookup by reference number returning incorrect records #1783: Fixed transaction reference lookup by adding input validation, trimming whitespace, and supporting reference-number fallback lookups in single-transaction queries.
• [Bug] Prevent SQL injection vulnerability in dynamic compliance search query #1784: Prevented SQL injection in dynamic compliance document queries by escaping LIKE wildcards (%, _, \) with explicit ESCAPE '\\' clauses and enforcing parameterized input constraints.
• [Bug] Fix session timeout redirect loop on admin dashboard #1785: Fixed session timeout redirect loop on administrative HTML dashboards by terminating recurring polling intervals on 401/403 status codes and displaying an inline session expiration message.
• [Bug] Fix validation of phone numbers with country prefix overrides #1786: Fixed phone number validation and network provider matching for numbers with country prefix/region overrides (e.g. Uganda, Ghana, Tanzania, Cameroon).

Why

1. [Bug] Fix transaction lookup by reference number returning incorrect records #1783 (Transaction Reference Lookup): Unsanitized or untrimmed reference number parameters caused lookups to fail or return mismatched records when whitespace or reference-number-formatted identifiers were supplied.
2. [Bug] Prevent SQL injection vulnerability in dynamic compliance search query #1784 (SQL Injection in Compliance Search): Unescaped wildcard characters (%, _, \) in dynamic ILIKE compliance document queries allowed arbitrary pattern matching and potential query manipulation.
3. [Bug] Fix session timeout redirect loop on admin dashboard #1785 (Session Timeout Loop on Dashboard): Background polling on the admin dashboard (setInterval) continued issuing requests after session expiration, triggering recurring 401 unauthenticated errors and potential redirect loops.
4. [Bug] Fix validation of phone numbers with country prefix overrides #1786 (Phone Number Validation Overrides): Phone validation and provider prefix matching failed for valid national-format numbers when operating under country prefix overrides because national prefixes were not resolved against the target provider's country calling code before prefix verification.

Implementation

• src/models/transaction.ts: Validated input string types and trimmed reference numbers in findByReferenceNumber and buildListWhere.
• src/controllers/transactionController.ts: Added fallback lookup to findByReferenceNumber in getTransactionHandler when findById returns null.
• src/utils/transactionFilters.ts: Added support for referenceNumber, reference, and reference_number query parameters with string trimming.
• src/utils/referenceGenerator.ts: Standardized reference date generation using UTC calendar methods to avoid cross-timezone day boundary drifts.
• src/models/complianceDocument.ts: Escaped special characters (%, _, \) and added ESCAPE '\\' to ILIKE search clauses in list().
• src/routes/admin.ts: Added 401/403 session expiration checks in HTML dashboard views (/financial/dashboard, /audit-logs/view, /compliance/knowledge-base) to cancel active polling timers and display an explicit login link without redirect loops.
• src/utils/phoneUtils.ts: Updated validatePhoneProviderMatch, detectProvider, and formatPhoneForProvider to accept optional countryOverride?: CountryCode and normalize local/national phone numbers by resolving country calling codes before checking network prefixes.
• src/utils/tests/phoneUtils.test.ts: Added comprehensive unit tests covering phone numbers with country prefix overrides across African provider regions.
