Add size & complexity labels to open issues on PD project board

### Overview

We need to add size and complexity labels to any open issues where they're missing, so that we can track project progress and velocity.

### Action Items
- [ ] Update the https://github.com/hackforla/peopledepot/issues/137 issue and then do this issue
- [ ] Note any open issues with missing size labels
- [ ] Add size labels to those issues using the following rubric (time for person to complete based on complexity) and in dialogue with Leads

| label | Description |
| ------------ | --------------------------------------- |
| size: 0.25pt | Can be done in 1.5 hours or less |
| size: 0.5pt | Can be done in 2-3 hours or less |
| size: 1pt | Can be done in 4-6 hours |
| size: 2pt | Can be done in 7-12 hours |
| size: 3pt | Can be done in 13-18 hours |
| size: 5pt | Can be done in 19-30 hours |
| size: 8pt | Can be done in 31-48 hours |
| size: 13+pt | Must be broken down into smaller issues |
| complexity: small | Easy |
| complexity: medium | More difficult |
| complexity: large | Requires experienced developer |
