Sales rep contact info

The sales rep block on a distributor's page tells Alba where to send the actual order when you confirm a proposal:

• Rep email — the order email goes here. Include a fallback to a general orders@ if you have one.
• Rep phone — if set, Alba also texts the rep the order summary with a one-tap confirm link. Useful for reps who reply by phone, not email.
• Account number — included in the order email so the rep can match it to your account in their system.
• Payment terms — Net 30, COD, etc. Shown on the order email so the rep doesn't have to look it up.
• Preferred delivery day — overrides the calendar's delivery_days for proposals targeting your specific account when you have a preferred day among multiple available.

Anything missing? Edit and save. Alba uses the new values from the next proposal onwards.
