Update flake inputs, deduplicate beads/gastown package definitions

- Update beads and gastown flake inputs and vendorHashes
- Remove merged-upstream patches for gastown and beads
- Deduplicate beads/gastown build definitions in home role by using
  callPackage to reference shared packages/ definitions
- Pin dolt to v1.82.4 (gastown requires >= 1.82.4)
