Closes #86

[Copilot]

Pull request overview

Fixes frontend numeric input UX so users can type/edit numbers without immediate coercion (which can introduce unwanted leading/default 0 values), and adds basic validation/guardrails before saving.

Changes:

• Introduce “draft string” state for several numeric inputs (to avoid forced numeric coercion while typing) and add form validation + disabled Save behavior.
• Add validation gating for spray threshold edits in the prescription thresholds modal.
• Remove native number steppers globally via CSS.

thresholdsAreValid currently requires all three draft fields to be non-empty finite numbers. However openThresholdsModal initializes missing values as empty strings and saveThresholds explicitly treats empty strings as “keep current saved value”. As a result, users can no longer leave any threshold blank (even to keep the current value), and the Save button stays disabled. Consider treating empty strings as valid (e.g., validate each field as either blank or a finite >= 0 number) to match the save/merge behavior.
