feat(freight): track onboarding-phase edit history for companies

Ticket #238 — pre-approval edits and document uploads write straight
to the live company row with no approval gate and, until now, no
trace. Adds an append-only company_revisions log (diffed field
changes, document uploads) recorded from updateProfile and
uploadCompanyDocuments, exposed via GET /companies/:id/revisions and
shown as "Version history" on the backoffice customer detail page.
