Standardise logging, error message formatting,wrapping etc across codebase

### Describe the feature you'd like to have #
Standardised logging, error message formatting,wrapping etc across code base.

Currently, we use a variety of logging (Info,Debug,Error) and error formatting (`"failed with ... with err %w"` , `"failed with ... : %w"` ).
Its good to document these and keep it uniform across codebase.

### How will we know we have a good solution? (acceptance criteria)

- Standard documented format used across code base.

#### Add a list of criteria that should be met for this feature to be useful

- Ease of interpretation error/log messages and implementation.
- Consensus and acceptance of the standardised format.

Please comment your suggestions below.

Review the existing logging calls and error-formatting patterns across the codebase, then read the issue discussion for proposed conventions. Done means a documented standard is agreed on and the codebase follows the accepted logging and error-message format.
