Pull request description:

The unserialization flows of the PSBT types work based on few underlying assumptions of functions from `serialize.h` & `stream.h` that takes some to understand when read the first time.

Add few comments that highlight these assumptions hopefully making it easier to grasp. Also, mention key/value format types as per BIP 174.

The short version

What changed, and why it matters

This commit is a documentation-only change for Bitcoin Core. It adds comments explaining how PSBT (Partially Signed Bitcoin Transaction) data is read from serialized bytes, with no changes to actual code behavior. The surrounding merge commit also includes a very large number of unrelated file additions (build files, templates, docs, etc.), but the titled change itself is purely explanatory comments.

Recommended action

No security action needed. This is a non-functional documentation/comment change. Reviewers may optionally verify the accuracy of the added comments against BIP 174 and the serialization helpers.

Security signals we found

No strong security signals were identified.
