Combines tiberius-rs/tiberius#387 (correct escaping) and #388 (test coverage) -- neither alone was complete: #387 escapes an embedded `]` but ships no test, #388 has a test but doesn't escape `]`. Also resolves the same underlying bug reported separately in #296/#398. A column named after a reserved word or containing a space (e.g. `[End]`) broke bulk_insert, since the INSERT BULK/SELECT TOP 0 statement text that MetaDataColumn::Display generates from the server's own reported column metadata didn't quote the name at all. Now brackets it, doubling any literal `]` per SQL Server's own escaping rule for quoted identifiers (`]` -> `]]`), so a column that itself contains `]` can't break out of the quoted identifier into the surrounding statement text. Added regression tests in both tests/bulk.rs (a bulk_insert into an `[End] INT` column) and tests/query.rs (manually-bracket-quoted execute/query against the same), ported from #388. Confirmed the bulk.rs test fails without this fix ("Incorrect syntax near the keyword 'End'") and passes with it. Note: Client::bulk_insert_columns's caller-supplied column list (added this session, #359) is a related but separate gap -- it isn't bracket-quoted either, and fixing that needs to special-case the "*" wildcard so it isn't itself quoted. Left out of scope here to avoid touching that just-shipped, already-tested feature; worth a follow-up. Verified live against a real SQL Server (Azure SQL Edge via rustls): 292 tests total (202 in tests/query.rs, 90 in tests/bulk.rs). Also verified: cargo check across all 6 CI feature combinations, cargo clippy --all-targets, cargo fmt --check, and cargo test --lib (153 passing).

Changed the code to support spaces in column names in bulk insert.
