Zamil Majdy 423b22214a feat(blocks): Add Excel support to ReadSpreadsheetBlock and introduced FileReadBlock (#10393) ...

This PR adds Excel file support to CSV processing and enhances text file
reading capabilities.

### Changes 🏗️

**ReadSpreadsheetBlock (formerly ReadCsvBlock):**
- Renamed `ReadCsvBlock` to `ReadSpreadsheetBlock` for better clarity
- Added Excel file support (.xlsx, .xls) with automatic conversion to
CSV using pandas
- Enhanced parameter `file_in` to `file_input` for consistency
- Excel files are automatically detected by extension and converted to
CSV format
- Maintains all existing CSV processing functionality (delimiters,
headers, etc.)
- Graceful error handling when pandas library is not available

**FileReadBlock:**
- Enhanced text file reading with advanced chunking capabilities
- Added parameters: `skip_size`, `skip_rows`, `row_limit`, `size_limit`,
`delimiter`
- Supports both character-based and row-based processing
- Chunked output for large files based on size limits
- Proper file handling with UTF-8 and latin-1 encoding fallbacks
- Uses `store_media_file` for secure file processing (URLs, data URIs,
local paths)
- Fixed test input to use data URI instead of non-existent file

**General Improvements:**
- Consistent parameter naming across blocks (`file_input`)
- Enhanced error handling and validation
- Comprehensive test coverage
- All existing functionality preserved
