When bitshuffle page header corruption is detected, the current error
message only shows the corrupted values without any context about which segment
file is affected. This makes debugging very difficult.
This PR adds:
1. File path, page offset, page size, and page index to the error log in
FileColumnIterator::_read_data_page()
2. Enhanced error message in parse_bit_shuffle_header() to include
expected_padding, compressed_size, size_of_element, and data_size
3. Similar logging in IndexedColumnIterator for completeness
Example output after this change:
W20260130 16:40:19 column_reader.cpp:1517] failed to create ParsedPage,
file=/path/to/data/tablet_id/rowset_id.dat, page_offset=12345678,
