Question: cleanup of potentially unused <cinttypes> includes in db/blob headers

[arup-chauhan]

Description:
While working on #13365 and my related PR (#14334), I noticed some db/blob headers include both <cstdint> and <cinttypes>.

From a quick scan, several of these headers appear to use fixed-width integer types (uint32_t/uint64_t) but do not appear to use PRI*/SCN* format macros directly.

Would it be okay to remove where it is not needed, while keeping for type definitions?

I’m asking first to align with project preference, especially if any of these includes are intentionally retained for downstream compatibility/include-order reasons.

If helpful, I can send a focused PR limited to db/blob include cleanup.
