Medibase Medicines Integration

[rithviknishad]

Proposed Changes

• Adds Medibase Medicines static data
• Migrations to load it to MedibaseMedicine table
• In-memory table to search MedibaseMedicines based on name/generic/company.
• Old medicines are moved to medicine_old
• Updated discharge summary to show appropriate medicine.

Eg. discharge summary: 84115ae4-9636-4aac-948a-fb10445c89a41686141886.pdf

Migrations:

1. Rename field medicine to medicine_old
2. Alter field: medicine_old to be nullable and added field medicine as nullable not blank FK to MedibaseMedicine
3. Custom Migration that populates MedibaseMedicine table from static_data

Added migrations from fresh + used name as unique instead of medibase_id since that was a Mongodb thing.
