feat: added map method to query builders

[akorchyn]

• added map method to change the query result type if you want to construct it some other way around. These methods help to simplify mapping internally (more clean) and provide a big improvement in dev UX on fetching data.

• Bug-fixed Delegation::view_balance method that returned staked balance instead of unstaked.

Don't think it related to this PR, though

Don't think it related to this PR, though

actually , i went to workflows in the target branch to copy an up-to-date command to a local justfile to build documentation with, to look at doc comments added in target branch, and noticed it's out of sync with docs.rs directives in manifest,
so i think it's pretty much related to this pr, despite the referenced line being nowhere close to modified ones

besides, the commented structs/methods (e.g. in src/common/query.rs) reside in a private module, so their addition won't be checked for consistency in ci with cargo doc before attempting to publish
