Add program and enrollments concept

[DeeTheDev]

We implemented the concept of 'Programs' for members based on the Portland Water Bureau RAMP program pilot. In figuring out what a program is and reviewing the current backend components, we noticed that programs would remove a lot of complexity around member eligibility constraints, and the way we represent goods in member dashboards.

Eligibility constraints are technically duplicates of organization memberships, and both are used to verify a member. Instead, we replace eligibility constraints with programs. Members or organizations can be in program enrollments. Resources like food offerings and vendor services can be in programs. Changes include:

• Vendible::Grouping dashboard list is replaced by Program detail list that a member is enrolled in.
• offerings/vendor configs/vendor services/triggers Eligibility::Constraint associations are replaced with Programs
• members Eligibility::Constraint associations are replaced with Program::Enrollment, and organizations can be associated with program enrollments too
• Remove backend eligibility constraint models and references

Then the backend logic of member resource eligibility is replaced with, 'a user can access an offering/service if the user has an approved program enrollment (or the user is a verified member of an organization with an approved program enrollment) in an active program that is associated with the offering/service'.

---

Sets a 'now' key and API method helper in the env which we can use across the API and model layer of requests. This avoids many different definitions of 'now' within an endpoint/entity.

---

Admin pages replace eligibility constraints with programs and program enrollments. Also removes 'vendible groups', not necessary anymore.

---

Members with a positive ledger cash balance, will see their available amount on the top of the dashboard page
