0ea616a6ea feat: WhatsApp campaigns (#11910)
# Pull Request Template

## Description

This PR adds support for WhatsApp campaigns to Chatwoot, allowing
businesses to reach their customers through WhatsApp. The implementation
includes backend support for WhatsApp template messages, frontend UI
components, and integration with the existing campaign system.

Fixes #8465

Fixes https://linear.app/chatwoot/issue/CW-3390/whatsapp-campaigns

## Type of change

- [x] New feature (non-breaking change which adds functionality)
- [ ] Bug fix (non-breaking change which fixes an issue)
- [ ] Breaking change (fix or feature that would cause existing
functionality not to work as expected)
- [ ] This change requires a documentation update

## How Has This Been Tested?

- Tested WhatsApp campaign creation UI flow
- Verified backend API endpoints for campaign creation
- Tested campaign service integration with WhatsApp templates
- Validated proper filtering of WhatsApp campaigns in the store

## Checklist:

- [x] My code follows the style guidelines of this project
- [x] I have performed a self-review of my code
- [x] I have commented on my code, particularly in hard-to-understand
areas
- [ ] I have made corresponding changes to the documentation
- [x] My changes generate no new warnings
- [ ] I have added tests that prove my fix is effective or that my
feature works
- [ ] New and existing unit tests pass locally with my changes
- [ ] Any dependent changes have been merged and published in downstream
modules

## What we have changed:

We have added support for WhatsApp campaigns as requested in the
discussion.
Ref: https://github.com/orgs/chatwoot/discussions/8465

**Note:** This implementation doesn't exactly match the maintainer's
specification and variable support is missing. This is an initial
implementation that provides the core WhatsApp campaign functionality.

### Changes included:

**Backend:**
- Added `template_params` column to campaigns table (migration + schema)
- Created `Whatsapp::OneoffCampaignService` for WhatsApp campaign
execution
- Updated campaign model to support WhatsApp inbox types
- Added template_params support to campaign controller and API

**Frontend:**
- Added WhatsApp campaign page, dialog, and form components
- Updated campaign store to filter WhatsApp campaigns separately
- Added WhatsApp-specific routes and empty state
- Updated i18n translations for WhatsApp campaigns
- Modified sidebar to include WhatsApp campaigns navigation

This provides a foundation for WhatsApp campaigns that can be extended
with variable support and other enhancements in future iterations.

This PR introduces several improvements to the Captain AI dashboard
section:

- New billing page, with new colors, layout and meters for Captain usage
- Updated the base paywall component to use new colors
- Updated PageLayout.vue, it's more generic and can be used for other
pages as well
   - Use flags to toggle empty state and loading state
- Add prop for `featureFlag` to show the paywall slot based on feature
enabled on account
- Update `useAccount` to add a `isCloudFeatureEnabled`
- **Removed feature flag checks from captain route definitions**, so the
captain entry will always be visible on the sidebar
- Add banner to Captain pages for the following cases
   - Responses usage is over 80%
   - Documents limit is fully exhausted

d070743383 feat(ee): Add Captain features (#10665)
Migration Guide: https://chwt.app/v4/migration

This PR imports all the work related to Captain into the EE codebase. Captain represents the AI-based features in Chatwoot and includes the following key components:

- Assistant: An assistant has a persona, the product it would be trained on. At the moment, the data at which it is trained is from websites. Future integrations on Notion documents, PDF etc. This PR enables connecting an assistant to an inbox. The assistant would run the conversation every time before transferring it to an agent.
- Copilot for Agents: When an agent is supporting a customer, we will be able to offer additional help to lookup some data or fetch information from integrations etc via copilot.
- Conversation FAQ generator: When a conversation is resolved, the Captain integration would identify questions which were not in the knowledge base.
- CRM memory: Learns from the conversations and identifies important information about the contact.

6d3ecfe3c1 feat: Add new sidebar for Chatwoot V4 (#10291)
This PR has the initial version of the new sidebar targeted for the next major redesign of the app. This PR includes the following changes

- Components in the `layouts-next` and `base-next` directories in `dashboard/components`
- Two generic components `Avatar` and `Icon`
- `SidebarGroup` component to manage expandable sidebar groups with nested navigation items. This includes handling active states, transitions, and permissions.
- `SidebarGroupHeader` component to display the header of each navigation group with optional icons and active state indication.
- `SidebarGroupLeaf` component for individual navigation items within a group, supporting icons and active state.
- `SidebarGroupSeparator` component to visually separate nested navigation items. (They look a lot like header)
- `SidebarGroupEmptyLeaf` component to render empty state of any navigation groups.

a8c12ffb25 chore: update interpolation syntax for i18n files (#10198)
There were two warnings showing up on new teams page

1. `errorMessage` prop was getting invalid value, this was because were
short circuting the error message using `&&`, fixed it by using ternary
operator
2. `vue-i18n` has deprecated [rails
syntax](https://vue-i18n.intlify.dev/guide/essentials/syntax#rails-i18n-format),
fixed that warning by removing `%` before `{}` for interpolation

> Note: the `vue-i18n` deprecation needs to be handled, but we can do it
later
