Hide "Gewasresten achterlaten" input when crop residues are not applicable

[SvenVw]

Background & Motivation

In the fdm-app, when configuring or viewing cultivations, users are asked whether crop residues are left on the field ("Gewasresten achterlaten" / m_cropresidue).

However, for many cultivations, crop residues are either not applicable, do not exist, or have an effective organic matter (EOM) value of 0. When the cultivation catalogue indicates that b_lu_eom_residues === 0 (or null), checking this box has no impact on calculations or the organic matter balance. Displaying this input in these scenarios leads to a cluttered UI and can cause confusion for users (farmers and advisors).

Requirements

• Conditionally render or disable the "Gewasresten achterlaten" inputs based on the cultivation's properties.
• Look up the selected crop in the cultivation catalogue (b_lu_catalogue -> b_lu_eom_residues).
• If b_lu_eom_residues === 0 (or null), the input should be hidden (or clearly marked as non-applicable/disabled).
• Ensure that hiding the checkbox does not cause any React Hook Form / Zod validation errors. If hidden, the value should default to false gracefully upon submission.

Affected Areas

This input appears in several places across the application that need to be updated:

1. Cultivation Details Form

   • File: fdm-app/app/components/blocks/cultivation/card-details.tsx
   • Action: Hide the m_cropresidue checkbox (Label: "Gewasresten achterlaten") completely when b_lu_eom_residues === 0 with 'invisible' class.

2. Rotation Table Page

   • File: fdm-app/app/components/blocks/rotation/columns.tsx
   • Action: The "Gewasresten" column allows users to toggle m_cropresidue. For rows where the crop has b_lu_eom_residues === 0, this cell should not render an interactive checkbox/dropdown, but instead should hide it.
   • Related File: fdm-app/app/components/blocks/rotation/table.tsx

3. Validation Schemas & Actions

   • Files: fdm-app/app/components/blocks/cultivation/schema.ts and fdm-app/app/components/blocks/rotation/schema.ts
   • Action: Ensure that m_cropresidue can gracefully handle being omitted or implicitly set to false when the UI inputs are hidden.
   • Action handler: fdm-app/app/routes/farm.$b_id_farm.$calendar.field.$b_id.cultivation.$b_lu.tsx and rotation actions.

Technical Context

• The field in the database/schema is b_lu_eom_residues (from cultivations_catalogue).

Acceptance Criteria

• Users do not see the "Gewasresten achterlaten" checkbox in the Cultivation Details form for crops with b_lu_eom_residues === 0.
• In the Rotation Table, the "Gewasresten" input is hidden for applicable rows.
• Form submission works correctly regardless of whether the checkbox is visible, defaulting to false.
