fix(report_tables): match reports path anywhere in pathname for export

Remove anchored `^` from regex matching `/reports/:id` segment when
building export-all URL. Pathname may be prefixed (e.g. locale or
base path segment before `/reports/...`), so anchoring to start of
string caused match to fail and export link to be built incorrectly.
Unanchored pattern finds reports segment regardless of position.
