🏗️ Integrate lnschema-core into lamindb

[falexwolf]

lnschema-core is now integrated into lamindb and will enable better code architecture and project organization.

The present PR merely performs the integration without re-organizing code.

Note that while the new Django app is called lamindb instead of lnschema_core, we still refer to the schema as the "core" schema; mostly so that we can make this migration without making any changes to the hub.

The PR requires renaming tables in the instance SQL databases. They're now prefixed with lamindb_ instead of lnschema_core_. The change is automated and requires mere confirmation in a dialogue from the user upon connecting to an instance. It has already been performed for these instances:

• laminlabs/lamindata
• laminlabs/lamin-site-assets
• laminlabs/lamin-dev
• laminlabs/arrayloader-benchmarks

Needs:

• 🏗️ Integrate lnschema-core into lamindb lamindb-setup#921
• 🏗️ Integrate lnschema-core into lamindb bionty#177
• 🏗️ Integrate lnschema-core into lamindb wetlab#89
• 🏗️ Integrate lnschema-core into lamindb ourprojects#7
• 🏗️ Integrate lnschema-core into lamindb lamin-cli#100
• 🏗️ Integrate lnschema-core into lamindb clinicore#16

Addresses:

• https://github.com/laminlabs/pfizer-lamin-usage/issues/75
• POC: Use composition instead of inheritance for user-facing Record classes #2129
• and further-reaching goals

Materials:

• The previous repo https://github.com/laminlabs/lnschema-core keeps existing as a public archive
