fix: write Measurements rows by column name, not by position

Root cause: _row_for_measurement() returned a positional list based on
_measurement_columns() order, but the actual Google Sheet may have
columns in a different order (if the sheet was created before new
columns were added and _ensure_measurements_sheet() appended them
at the end rather than in the middle). Values ended up in wrong
columns — client_name, manager_tg_id etc. were misaligned, so
_handle_clients couldn't match any rows and returned an empty list.

Fix:
- _row_for_measurement() now returns dict {col_name: value}
- sheets.append_named_row() reads real headers from the sheet and
  builds the positional row accordingly — safe regardless of column order
- All three Measurements append calls updated to use append_named_row
