[ADD] stock_picking: Repeat fields on Picking Operations Report PDF

[ripil-odoo]

Purpose

The task requested that specific header fields remain visible on subsequent pages when a Picking Operations PDF report spans multiple pages. Currently, these details are only visible on the first page when the table extends to the next page.

Changes Made

• Template Inheritance: Inherited the default template stock.report_picking.
• Header Relocation: Moved the o_stock_report_header_row elements into a <tr> inside the table header (<thead>).
• Page Persistence: Using standard wkhtmltopdf behavior, placing this data inside the <thead> forces the browser engine to repeat the header fields automatically on every new page break.

Technical Details

Model: stock.picking
Custom Template: report_stockpicking_operations_inherited

Why

• wkhtmltopdf repeats any content wrapped inside a <thead> tag at the top of every new page when a table overflows. Moving the data here solves the client's request using standard HTML behavior without the need for complex custom logic.
• Rather than rebuilding the layout this change targets the structure directly to ensure the data is present on page 2 and beyond.

Verification Steps

1. Install Custom Picking Operation Report Header module from Apps.
2. Go to Inventory -> Receipts.
3. Select or create a picking record (stock.picking) with enough operations/lines to span across at least 2 pages.
4. Click Print -> Picking Operations.
5. Verify that the document fields repeat at the top of the second page exactly as they appear on the first page.
