The `UNKNOWN_DESCRIPTOR` error comes from the
`WalletDescriptor::DeserializeDescriptor` std::ios_base
exception, which contains further information about the
parsing error.

1d207e3931 wallet: do not allow loading descriptor with an invalid ID (furszy)
Pull request description:
Aiming to fix#27915.
As we re-write the descriptor's db record every time that
the wallet is loaded (at `TopUp` time), if the spkm ID differs
from the one in db, the wallet will enter in an unrecoverable
corruption state (due to the storage of a descriptor with an ID
that is not linked to any other descriptor record in DB), and
no soft version will be able to open it anymore.
Because we cannot change the past, to stay compatible between
releases, we need to always use the apostrophe version for the
spkm IDs.

fa38d86235 Use only Span{} constructor for byte-like types where possible (MarcoFalke)
fa257bc831 util: Allow std::byte and char Span serialization (MarcoFalke)
Pull request description:
Seems odd to require developers to cast all byte-like spans passed to serialization to `unsigned char`-spans. Fix that by passing and accepting byte-like spans as-is. Finally, add tests and update the code to use just `Span` where possible.

Code review ACK fa38d86235. This looks great. The second commit really removes a lot of boilerplate and shows why the first commit is useful.

If the computed descriptor's ID doesn't match the wallet's
DB spkm ID, return early from the loading process to prevent
DB data from being modified in any post-loading procedure
(e.g 'TopUp' updates the descriptor's data).
Instead of iterating the database to load the wallet, we now load
particular kinds of records in an order that we want them to be loaded.
So it is no longer necessary to iterate the entire database to load the
wallet.
Instead of dealing with these records when iterating the entire
database, find and handle them explicitly.
Loading of OLD_KEY records is bumped up to a LOAD_FAIL error as we will
not be able to use these types of keys which can lead to users missing
funds.
Instead of loading active spkm records as we come across them when
iterating the database, load them explicitly.
Due to exception handling changes, deserialization errors are now
treated as critical.
Instead of loading address book records as we come across them when
iterating the database, load them explicitly
Due to exception handling changes, deserialization errors are now
treated as critical.
The error message for noncritical errors has also been updated to
reflect that there's more data that could be missing than just address
book entries and tx data.
Instead of loading descriptor wallet records as we come across them when
iterating the database, loading them explicitly.
Exception handling for these records changes to a per-record type basis,
rather than globally. This results in some records now failing with a
critical error rather than a non-critical one.
