### What problem does this PR solve?
Issue Number: N/A
Related PR: N/A
Problem Summary: This adds a focused BE unit-test fixture for storage index
lifecycle coverage around inverted index probe events, patched tablet schemas,
variant sparse/nested metadata, and COUNT_ON_INDEX no-need-read-data behavior.
The tests cover index add/drop and build/drop on text and variant path indexes,
missing required variant columns, V1/V2 index storage files, rowset map updates
after schema patching, and red/green validation that COUNT_ON_INDEX reads only
rows filtered by an applied inverted index. The implementation records index
probe events for applied, fallback, and not-attempted column predicates,
preserves existing SegmentIterator debug points, skips missing physical columns
only when nullable/default columns make that valid, and resolves field_pattern
variant index build/drop against materialized paths.

clang-tidy could not analyze Doris headers due toolchain/PCH diagnostics
(`stddef.h` not found from `slice.h` and existing `core/types.h` NOLINT
parsing). A clang-tidy-16 probe also failed with incompatible PCH AST.
