<!-- Describe what has changed in this PR --> All new code is gated behind the frontend.accessHistoryFraction dynamic config. The new code is meant to be a port of the original FE code, but primarily executed by the History service moving forward. Because this change affects both FE and History, it requires a prolonged deprecation process where: - upon the 1st minor release (upcoming), the dynamic config must remain disabled by default - by the 2nd minor release, the dynamic config to be switched to be enabled by default - starting from the 3rd minor release, the deprecated code will be removed This change is staged into the following 4 major steps: - DEPRECATE - refactor FE logic/tests into deprecated files (no logic change) - DUPLICATE - dup deprecated logic to history service (verbatim copy/paste) - PLUMBING - introduce rpc and handlers along with basic necessities (hooking up) - IMPORTANT - call-by-call replacement (requires careful review) <!-- Tell your future self why have you made these changes --> This is a big refactor to move business logic from FE to History service. <!-- How have you verified this change? Tested locally? Added a unit test? Checked in staging env? --> - Ported FE unit tests to the History service layer - Spot checked by running in dev environment <!-- Assuming the worst case, what can be broken when deploying this change to production? --> **Potential risks** <!-- Is this PR a hotfix candidate or require that a notification be sent to the broader community? (Yes/No) --> **Is hotfix candidate?**
