Refactor schemas to place projects and commitments under capital namespace

[TangoYankee]

Description

"Project" is a generic term and we anticipate that we'll have a collision as soon as we start adding other types of "projects". We're adding "capital" as a way to specify the type of project that it is. We will apply the same treatment to "commitments". We need to update the drizzle schemas to reflect this

Acceptance Criteria

The project and commitment columns and tables are updated as follows:

• [x] project table -> capital_project table
• [x] project_fund table -> capital_project_fund table
  • [x] project_id column -> capital_project_id column
• [x] project_category enum -> capital_project_category enum
• [x] project_fund_stage enum -> capital_project_fund_stage
• [x] project_checkbook table -> capital_project_checkbook table
  • [x] project_id column -> capital_project_id column
• [x] commitment table -> capital_commitment table
• [x] commitment_type table -> capital_commitment_type table
• [x] commitment_fund table -> capital_commitment_fund table
  • [x] commitment_id column -> capital_commitment_id column
• [x] fund_category enum -> capital_fund_category enum
• [x] Any other names that have been overlooked in making this ticket
