Further information:

This pull request introduces new tile deletion parameter schemas and types, and refactors the SourceType constant and type to the core constants module for better consistency and reuse. The main changes focus on schema validation for tile deletion operations and code organization.

Schema and Type Additions:

• Added tileRangeSchema, tilesDeletionParamsBaseSchema, and provider-specific schemas (s3TilesDeletionParamsSchema, fsTilesDeletionParamsSchema) using zod for validating tile deletion parameters in src/schemas/core/tile.schema.ts.
• Introduced TypeScript types TilesDeletionParams and TileRange inferred from the new schemas in src/types/core/tile.type.ts.

Constants Refactoring:

• Moved the SourceType constant and type definition from src/constants/export/constants.ts to src/constants/core/constants.ts for centralized usage and maintainability [1] [2].
• Added MAX_ZOOM_LEVEL constant to src/constants/core/constants.ts for use in tile validation.
