fix(reports): BoL PDF — t-field needs dotted path, branch on delivery_address_id

The Bill of Lading template assigned a temp variable
`<t t-set="dest" t-value="doc.delivery_address_id or doc.partner_id"/>`
and then tried `<div t-field="dest" .../>`. Odoo 19 QWeb asserts
t-field must be `record.field_name` (have a dot) — the temp variable
form fails compilation and the report renders as a multi-page
"Oops! Something went wrong" PDF stuffed with the traceback.

Fix: branch with `t-if`/`t-else` and call `t-field="doc.delivery_address_id"`
or `t-field="doc.partner_id"` directly. Same pattern in both header
and second-page-header sections (lines 49/235).

Verified: BoL render goes from 39 KB error page to 138 KB clean PDF.
