fix(#2203): traceability parser matches REQ-IDs in any column (#2234)

* fix(#2203): traceability parser matches REQ-IDs in any column, not just the first

The traceability table-row parser required the REQ-ID in the first column
(`^|  REQ-ID |`). A table that leads with a status column (e.g. `| ☐ | REQ-01 |`) matched zero rows, so phase complete warned every body REQ-ID was missing.
Match REQ-IDs in any pipe-delimited cell (drop the ^ anchor).

Closes #2203
