feat: initialize events app with calendars, slots, tickets, and internal API

Extract events/calendar functionality into standalone microservice:
- app.py and events_api.py from apps/events/
- Calendar blueprints (calendars, calendar, calendar_entries, calendar_entry, day, slots, slot, ticket_types, ticket_type)
- Templates for all calendar/event views including admin
- Dockerfile (APP_MODULE=app:app, IMAGE=events)
- entrypoint.sh (no Alembic - migrations managed by blog app)
- Gitea CI workflow for build and deploy

+# Events App
+
+Calendar and event booking service for the Rose Ash cooperative platform.
+
+## Overview
+
+The events app provides calendar-based event booking with flexible slot management.
+It runs as a standalone Quart microservice, part of the multi-app coop architecture.
+
+## Structure
+
+```
+app.py              # Application factory and entry point
+events_api.py       # Internal JSON API (server-to-server, CSRF-exempt)
+bp/                 # Blueprints
+  calendars/        # Calendar listing
+  calendar/         # Single calendar view and admin
+  calendar_entries/ # Calendar entries listing
+  calendar_entry/   # Single entry view and admin
+  day/              # Day view and admin
+  slots/            # Slot listing
+  slot/             # Single slot management
+  ticket_types/     # Ticket type listing
+  ticket_type/      # Single ticket type management
+templates/          # Jinja2 templates
+  _types/           # Feature-specific templates
+```
+
+## Running
+
+```bash
+# Set required environment variables (see .env.example)
+export APP_MODULE=app:app
+hypercorn app:app --bind 0.0.0.0:8000
+```
+
+## Docker
+
+```bash
+docker build -t events .
+docker run -p 8000:8000 --env-file .env events
+```
+
+## Notes
+
+- This app does **not** run Alembic migrations. Database schema is managed by the blog app.
+- Internal API endpoints under `/internal/events/` are used by the cart app for cross-service communication.
+- Depends on shared packages (`shared/`, `models/`, `config/`) from the main coop monorepo.
