💰 Budget Limits & Usage Dashboard
* Added: Budget limits — set daily/monthly caps on token usage and dollar spend for your AI chatbot from Settings → Usage & Moderation. When exceeded, the chatbot widget hides completely or falls back to showing only the WhatsApp CTA button.
* Added: Server-side pre-render check — budget limits are evaluated at page load so new visitors never see the AI chat widget when the budget is already exhausted. Admins always see the widget for testing.
* Added: Monthly usage summary in the Usage dashboard — select any month to view total input/output/combined tokens, estimated cost, conversation count, and a per-model breakdown table.
* Improved: “When limit is reached” behavior for budget limits now supports two modes: hide chatbot entirely, or show WhatsApp button only (requires WhatsApp CTA configured in bot settings).

4.1.1

• Added: OpenAI GPT-5.4 family — gpt-5.4 (1M context, $2.50/$15), gpt-5.4-mini (400K, $0.75/$4.50), and gpt-5.4-nano (400K, $0.20/$1.25). GPT-5.4 is now the default model for new bots.

🎯 Lead Capture — Major Overhaul
* Added: Inline lead forms (show_form) — the bot displays a styled form directly inside the chat widget. Visitors fill it out and submit without leaving the conversation.
* Added: Multiple Lead Lists — create independent lists, each with its own fields, destination, form design, bot assignment, and notifications.
* Added: Form Appearance customization per list — display mode (full/compact), custom HTML header, submit button text, success message, background color, and button color.
* Added: Live form preview panel in admin — see real-time changes to form appearance, fields, types, and required markers as you edit.
* Added: Custom field types — Text, Email, Phone, Textarea, Number, and URL with proper validation and mobile keyboard support.
* Added: Required field support — mark fields as mandatory with red asterisk indicator and client-side validation.
* Added: Bot assignment per list — assign a list to all bots or restrict it to a specific bot for multi-bot setups.
* Added: List name column in leads table and list filter for multi-list management.
* Added: Total leads footer row in lists table with global count.

* Improved: Chat input is temporarily disabled while the inline form is visible to focus visitor attention.
* Improved: Form submit shows a customizable success message with green checkmark, then conversation resumes normally.
* Fixed: Lead list filter and per-list count now work correctly (list_id properly stored on capture).

• Added: File & Image Uploads — visitors can now send photos (JPG, PNG, WebP) and PDF documents directly in the chat widget via a new 📎 attachment button.
• Added: AI Vision support — uploaded images are sent to the AI model’s vision capability (GPT-4o, Claude Sonnet/Opus, Gemini Pro/Flash) for real-time visual analysis.

• Added: Automatic image optimization — uploaded images are resized (max 1536px) and compressed to reduce API costs and speed up processing.

• Added: Admin log file indicators — conversation log list shows 📎 icon for sessions with attachments; detail view shows clickable thumbnails with secure full-size preview (base64 data URI, no public file exposure).
• Added: Per-bot upload configuration — enable/disable uploads, select allowed file types (PDF, JPG, PNG, WebP), and set max file size (1–20 MB) independently for each bot.

Third-party plugins can hook into aichat_after_purge_cache.
• Added: View and Edit buttons for indexed documents in Training → Context — inspect individual chunks, spot indexing errors, and surgically edit specific chunks with automatic re-embedding on save.

• Added: Email form mode collects email (required), name, and phone (both optional toggles with configurable placeholders).
• Added: GDPR Contacts tab under Leads — view, search, delete, bulk-delete, and export contacts captured via the email form. No plan limits apply.
