Extract and store all values from “Recommendations based on generic formulas”

[abdelghanibelgaid]

Add support to parse and store all values shown in the “Recommandations basées sur les formules génériques” block. This section includes fertilizer recommendations and cost information, and all values should be extracted as structured data.

Example values to extract and store:

• 1.41 qx/ha
• TSP
• base fertilizer
• 3.18 qx/ha
• Ammonitrates
• top-dressing fertilizer
• 858.9 dh/ha

Expected behavior:

• Detect the “Recommandations basées sur les formules génériques” section
• Extract all recommendation lines and the cost value
• Store them as structured fields in the parsed output
• Gracefully handle cases where the section is missing

The screenshot below shows the generic formula recommendation block to parse.

I’d like to take this issue. I’ll implement a focused, backward-compatible parser update that returns an ordered generic_formula_applications list (quantity, canonical unit, product, normalized/raw application role, and raw source text) plus scalar cost amount/currency/basis/raw fields. Missing or partially malformed generic-formula blocks will not break the existing N/P/K recommendation workflow. The contribution will include parser, client/batch, JSON/CSV serialization, tests, and documentation. The broader price-aware optimizer will be proposed as a separate follow-up issue.
