feat(dashboard): translation management

[chrismclarke]

Is your feature request related to a problem? Please describe.
Currently all translations are managed using google sheets, which requires multiple manual steps to integrate into the app. Ideally a minimal translations management system should be included in the admin dashboard

Describe the solution you'd like

• Create translations module in dashboard apps\picsa-apps\dashboard\src\app\modules
• Add routing and home page for created module and sidebar link in apps\picsa-apps\dashboard\src\app\app.component.ts
• Create db table with columns for id and translations by country/language codes (e.g. en, mw_ny, zm_ny)
• Create / (home) page component to list all translations from db (can just manually populate a couple translations to db for testing, will migrate full list later)
• Create /edit page and ui to create and edit translations

Additional context

• See docs for running server locally: https://docs.picsa.app/server
• Dashboard can be run via yarn start:dashboard, codebase in apps\picsa-apps\dashboard
• Examples of translation strings currently used in the app (exported from google sheet) can be found in libs\i18n
• Some example of interacting with server/services can be seen in the resources module of the dashboard codebase apps\picsa-apps\dashboard
