fix: add X-Tigris-Consistent headers to all rclone commands

Users outside the US (origin region: iad) get stale reads from Tigris
edge cache, causing bisync to miss updates or report no changes.

Adds `X-Tigris-Consistent: true` headers to project_sync, project_bisync,
project_check, and project_ls to bypass edge caching and force origin reads.

Closes #557
