feat: update TokenInfo to dump all token fields (#914)

[Om7035]

Description

This PR updates the __str__ method of the TokenInfo class to include all available token fields in its string representation. Previously, several important fields such as custom_fees, various keys (admin, kyc, freeze, etc.), and status flags were missing from the output, making debugging and logging less informative.

The following fields have been added to the __str__ output:

• custom_fees
• All keys: admin_key, kyc_key, freeze_key, wipe_key, supply_key, metadata_key, fee_schedule_key, pause_key
• Statuses: default_freeze_status, default_kyc_status, pause_status
• Auto-renew details: auto_renew_account, auto_renew_period
• expiry
• supply_type

@exploreriii need your help
I'm encountering a persistent issue with the PR Formatting / Changelog Check workflow. Despite adding a new entry under the [Unreleased] section in CHANGELOG.md (as seen in the latest commits), the check continues to fail with "No line-level additions detected".

I have:

• Verified the entry is under ## [Unreleased].
• Ensured it is a new line with a bullet point.
• Tried re-formatting and amending the commit.
• Verified the diff locally shows the added lines.

This same behavior has occurred on another recent PR (#927) of mine as well. Could you please take a look? It seems like the workflow might not be picking up the changes correctly or there might be a subtle formatting requirement I'm missing.

Hi @Om7035
Please be sure to update the unit and integration tests with your new functionality.

You'll need to:
Review existing unit and integration tests for token info.
Update all instances that are checking string representation
For example:
tests/unit/test_token_info.py::test_str_representation
Ensure it includes all the new fields

This is why your workflows are failing

Scan to the bottom of the integration and unit test sections and see the full error messagae
