fix(widgets): add multi-database compatibility to all dashboard widgets

Browse Source 
Replace SQLite-specific functions with database-agnostic expressions to support
  MySQL, SQLite, PostgreSQL, and SQL Server across all Filament dashboard widgets.

  - Fix strftime() date formatting in SubscriptionMetrics, RevenueMetrics, and TrialPerformance
  - Fix CAST AS REAL syntax in ChurnAnalysis widget
  - Add getDateFormatExpression() method for date function compatibility
  - Add getCastExpression() method for CAST syntax compatibility
  - Support MySQL/MariaDB, SQLite, PostgreSQL, and SQL Server drivers
  - Maintain identical functionality across all database types

  Fixes multiple SQLSTATE[42000] syntax errors when using MySQL/MariaDB databases.
