feat(standards): prefix account components with miden::standards namespace

[Himess]

Closes #2399

[PhilippGackstatter]

Thank you! Let's wait for #2373 to be merged and rebase on top of it once it is.

[Himess]

Hey @PhilippGackstatter, I noticed this PR has conflicts with next after #2373 landed.
The AccountComponentMetadata API changed to a builder pattern and AccountComponent::new now takes metadata as a 3rd argument, so the .with_metadata() approach here no longer applies.

Also, the current NAME constants on next are short-form ("miden::basic_fungible_faucet", "miden::basic_wallet") rather than the full library path ("miden::standards::account_components::faucets::basic_fungible_faucet") that this PR and #2399 propose.

Should I rebase and adapt to the new API, or has the naming direction changed since the issue was opened?

[PhilippGackstatter]

Hi @Himess, I think we should rebase and adapt to the new API. I also still think we should use the full library path instead of a short form one.

[Himess]

Hi @PhilippGackstatter wdyt about new changes ? Is it good or ?

[Himess]

Note: the enforcement in AccountComponent::new (checking that metadata name is a prefix of the library path) is left as a follow-up, since it requires fixes across multiple crates (miden-agglayer, testing components, etc.).
