This commit introduces a 'Contact Sales' modal on the web development page, allowing users to inquire about specific service plans.
- The pricing plan buttons now trigger this modal, pre-filled with the selected plan's details.
- Users can add custom remarks to their inquiry.
- On submission, a pre-formatted message is generated and opened in WhatsApp using a new `useWhatsAppMsgSender` composable.
- Adds `NUXT_PUBLIC_WHATSAPP_NUMBER` to the runtime configuration.
- Refactors content validation by introducing Zod schemas for `PricingPlan` and `Button` props to improve type safety.
- Adds new i18n keys for the modal interface and message templates.
This commit introduces a new page at `/webDev` to display web development services and pricing plans.
To support this, a new reusable composable `useLocalizedCollection` has been created to simplify fetching localized content from Nuxt
Content. The index page has been refactored to use this new composable.
- Adds `webDev.vue` page and corresponding `webDev.yml` content files for EN and ZH.
- Defines a Zod schema in `content.config.ts` for the new content type.
- Updates the navigation link to point to the new page.
