Propagate and handle errors in database and static file services

[Rjected]

Some of the static file service and database service methods have error return values, although they do not get propagated and probably need to be handled.

See:

reth/crates/engine/tree/src/static_files.rs

Line 183 in 068220b

.expect("todo: handle errors");

So, we will need to check the failure modes which would cause these errors, and either handle or propagate them.
