build: fix yarn warnings + align typescript version with core/snaps

[ccharly]

Just fixing yarn warnings by updating some deps

Important

We previously upgraded to ts 5.6.3 as this was a suggestion that would get in pair with the new usage of
ts-bridge, but none of our core monorepos are using this version, so I prefer to align it to follow the same pattern everywhere!

Note

Medium Risk
Moderate risk because it changes the TypeScript compiler version across workspaces, which can affect typechecking output and build behavior, though no runtime code paths are modified.

Overview
Aligns the monorepo’s toolchain to reduce yarn warnings by downgrading typescript from ~5.6.3 to ~5.3.3 across the root and multiple packages (including adding typescript where it was missing).

Bumps the formatting tool oxfmt to ^0.45.0 and updates yarn.lock accordingly, plus a small refactor in hd-keyring.test.ts and money-keyring.test.ts to avoid direct indexed access in assertions.
