refactor(db):update schema and fix foreign key references (#159)

This pull request includes significant changes to the database schema
and seed data scripts, focusing on refactoring table structures,
updating foreign key relationships, and enhancing the seed data. The
most important changes include the renaming and restructuring of tables,
the addition of new columns, and the removal of certain tables and
columns.

### Database Schema Changes:

* `database/start-scripts/0-init.sql`: 
- Renamed `task_types` to `tasks`, `pruning_types` to `element_types`,
and added new columns such as `description` and `require_tree_type`.
Removed `photo_id` and associated foreign key constraints from multiple
tables.
- Updated the `zones` table structure by adding new columns and
modifying foreign key relationships. Removed the `zones_predefined` and
`routes` tables.
- Added `deleted_at` and `updated_at` timestamps to several tables
including `work_reports`, `work_report_photos`, `sensors`, and
`sensor_history`.

### Seed Data Changes:

* `database/start-scripts/1-seed.sql`:
- Added seed data for `element_types`, `tasks`, `zones`, and `elements`.
Updated the seed data for `work_orders`, `work_orders_users`, and
`work_reports`.

These changes aim to streamline the database structure, improve data
integrity, and enhance the initial dataset for better testing and
development.
