CHORE: Organise content of json meta into separate files

[kriptonian1]

Description

Right now adding new content to constants/json-schema-meta.ts is kind of ugly, the meta description for all the flows are in one single file, it would be more organized if we had different flow in there own files example, we can migrate constants/json-schema-meta.ts to constants/meta/json-schema-meta.ts and inside that we can have constants/meta/keyboard-flow-meta.ts etc.

is this the solution you want?

index.ts--> all exported metadata
json-schema.ts--> your schema given
