bf0efb4fc7 scripted-diff: Modernize naming of nChainTx and nTxCount (Fabian Jahr)
72e5d1be1f test: Add basic check for nChainTx type (Fabian Jahr)
dc2938e979 chainparams: Change nChainTx to uint64_t (Fabian Jahr)
Pull request description:
This picks up the work from #29331 and closes #29258.
This simply changes the type and addresses the comments from #29331 by changing the type in all relevant places and removing unnecessary casts. This also adds an extremely simple unit test.
Additionally this modernizes the name of `nChainTx` which helps reviewers check all use of the symbol and can make silent merge conflicts.
