Polish public forms for faster, clearer completion #211

Goal

Bring Sea Saba's public forms up to the same quality bar as the site's visual design.

Scope

Audit contact, inquiry, booking-adjacent and other public forms for:

• correct input types and autocomplete attributes
• mobile keyboard behavior
• field grouping and progressive disclosure
• inline validation timing
• error placement
• clear required/optional labeling
• submission acknowledgement
• disabled/loading states
• success confirmation
• preserving entered data after recoverable errors

Acceptance criteria

• Autofill/autocomplete metadata is correct
• Validation is helpful and does not nag prematurely
• Submit actions acknowledge input immediately
• Recoverable errors do not unnecessarily wipe fields
• Mobile keyboard/input types are appropriate
• Error and success messages are accessible
• No backend/business-rule changes
