Fix 3 GHA test failures: sort redirect bug, column name portability

- sort_coordinates_bash: fix in-place redirect that truncated input file
  before grep could read it (write to temp, then move back)
- sort_coordinates_bash: validate column names exist in header before
  accessing cDict, preventing cryptic "subscript out of bounds"
- construct_query: validate start/end aren't NA before calling IRanges
- All tests: detect position column dynamically (POS or BP) instead of
  hardcoding, fixing failures when echodata uses either name
- test-run_bgzip: use .tsv instead of .tsv.gz to avoid double-compression
- test-convert: replace destructive tempdir cleanup with targeted removal
