Description

FE PR : juspay/hyperswitch-control-center#3505
This pull request makes significant updates to the dashboard configuration and theming system. The main changes include a major refactor of the dashboard.toml file to reorganize endpoints and feature flags, and the introduction of a new dashboard_theme.json file to centralize and modernize theme settings. These changes improve maintainability, flexibility, and clarity in how the dashboard's appearance and features are configured.

Configuration and Feature Management:

• Refactored config/dashboard.toml:
  • Removed the [default.theme] section and moved theme-related settings to a new JSON file.
  • Updated and reorganized [default.endpoints] with new URLs and additional keys for certificates, analytics, and third-party integrations.
  • Expanded [default.features] with new feature flags (e.g., branding, mixpanel, feedback, global_search, transaction_view, custom_webhook_headers, etc.) and restructured existing flags for better clarity and future scalability.
  • Added [default.merchant_config.whitelist] and [default.merchant_config.blacklist] sections to support granular merchant-specific feature access control.

Theming and UI Customization:

• Added config/dashboard_theme.json:
  • Introduced a new JSON-based theme configuration with structured settings for colors, sidebar, typography, buttons, borders, and spacing.
  • Centralized all UI theming options to make it easier to update the dashboard's look and feel without modifying TOML files.
  • Provided placeholders for faviconUrl and logoUrl to further support branding customization.
