🐛 Metadata Validation Issues in Outcome and Live Voting

### Context

#### 1. Live Voting
- According to the [metadata error condition: Data Not Verifiable](https://docs.gov.tools/cardano-govtool/using-govtool/dreps/drep-error-conditions#:~:text=the%20DRep%20spec.-,Data%20Not%20Verifiable,-The%20data%20that), if the hash does not match the hash of the metadata URL and the data format is incorrect, the validation API should return **"Invalid hash"**.
- However, in live voting, when governance action metadata validation fails due to an incorrect hash and governance action format, it incorrectly returns **"Data formatted incorrectly"** instead of **"Data not verifiable"**.

#### 2. Outcomes
- As per the [metadata error condition: Data Formatted Incorrectly](https://docs.gov.tools/cardano-govtool/using-govtool/dreps/drep-error-conditions#:~:text=they%20originally%20registered-,Data%20Formatted%20Incorrectly,-The%20data%20that), if the hash matches the metadata URL hash but the data format is invalid, it should return **"Data formatted incorrectly"** instead of valid metadata.
- Example request:

```
- Expected response: **"Incorrect Format"** with `"metadataValid": false`.
- Actual response:
```json

```
- This indicates that **"Data formatted incorrectly"** validation is missing in outcome metadata validation.

Additionally, there is an issue where the **breadcrumb title remains stuck in a loading state** and displays an empty title for incorrectly formatted governance actions.

### Actual Behavior
- In live voting, metadata validation incorrectly returns **"Data formatted incorrectly"** instead of **"Data not verifiable"** when the metadata hash does not match the hash of the metadata URL.
- The **"Data formatted incorrectly"** validation is missing in outcome metadata validation.

### Expected Behavior
- The system should implement **proper metadata validation** for both **live voting and outcomes** to ensure accurate error handling.
