feat!: migrate from Moment to Tempo

[ghiscoding]

• after more Googling, I found Tempo and I can finally migrate away from MomentJS. Tempo is simple, is ESM, is small and has all necessary functions to replace Moment
• by removing Moment (finally), we also get a much smaller build (not surprisingly since it's ESM)
• Few notes about Tempo
  1. it uses the exact same format tokens as Moment
  2. it doesn't support multiple formats like Moment did for parsing with/without zero padding but that doesn't matter since the non-padding token works for both usage (e.g. 'M/D/YY' will work for both '4/7/24' and '04/07/24'). With that in mind, I will use 'M/D/YY' to parse but I will use 'MM/DD/YY' to format date output

TODOs

• [x] investigate why locally a token is showing locally as a.m. but in CI it's showing as am (I would prefer same result on both side as am). I might need to open an issue on Tempo. I found out that it's caused by Intl.DateTimeFormat displaying a.m. when using "en-CA" but am when using "en-US" and so I'll use "en-US" everywhere to avoid such inconsistenticies
• [x] all unit tests should pass (except a.m. format, they all do)
• [x] all Cypress E2E tests should pass
• [ ] requires Migration Guide & other docs update
