feat(indexer): add token mints search capability

[Dairus01]

This PR implements a new search capability for the Indexer to find suitable carbon credits (Mint Token VPs). It adds a new backend API endpoint with comprehensive filtering (amount, date, geography, policy) and a corresponding frontend view.

• Add GET /entities/token-mints endpoint to Indexer Service with aggregation support
• Add SEARCH_TOKEN_MINTS message API and related interfaces/DTOs
• Add TokenMintsComponent to Indexer Frontend with sorting, filtering, and map link support
• Update Swagger documentation and e2e tests
• Fix geography population using ProjectCoordinates and add totalAmount aggregation
• Fix build configuration issues in indexer packages

Related issue(s):

Fixes #5021

Notes for reviewer:

• Endpoint: /entities/token-mints
• New View: "Carbon Credit Mints" under the Documents menu in the Indexer UI.
• Aggregation: The backend now performs a MongoDB aggregation to sum the total amount of minted tokens matching the filters.
• Geography: Coordinates are resolved via project relationships and formatted in the UI with a link to Google Maps.

Checklist

• Documented (Code comments, README, etc.)
• Tested (unit, integration, etc.)

@prernaadev01 quick question is your Guardian Community Bounty Program: Open Source Innovation still active

Hi @Dairus01 I have checked your changes and found the following bugs. Can you please have a look into them?

1. A couple of parameters are missing in the response body in comparison to what I can see in Swagger doc(missing parameters listed below):

• "policyId"
• "policyDescription"
• "geography"

2. According to the response example here, after totalAmount parameter, there should be no parameters, but in fact, there is one more parameter. Is it missing in Swagger doc or it should be removed from the response body?
   "order": { "consensusTimestamp": "DESC" }

3. On Carbon Credit Mints filters like Token Id, Policy ID, etc are displayed incorrectly and when you type any value, the filtering itself works well, but you cannot see the value you entered in the field(example below):

4. Also if I want to filter by Name(tokenName, or tokenSymbol) using keyword field, and type iRec Token, which is exact name, should the table be filtered by that value(because currently it shows empty table on UI and API(only tokenName, or tokenSymbol don't work, the rest seems to be working fine), below is the endpoint with filter example)?
   http://localhost:3021/entities/token-mints?keywords=["iRec Token"]

5. View Map button doesn't work and doesn't transfer to Google Maps to show location. Also the button itself doesn't look good, the view of it needs to be fixed(see the screenshot below).

6. When clicking on AMOUNT or DATE column on Carbon Credit Mints page to have ascending/descending sorting for the table, none of them(ascending/descending sort) works correctly(see the screenshot below). Can you please fix it?

7. @Pyatakov on Carbon Credit Mints page we have filter called Schema, but in the table itself we don't have such column. Should we introduce that column to be able to see that filtered schema is indeed included into the policy that was filtered? Also another question: we have filter called Geography, but in the table itself, we don't have column with such name, we have Coordinates column, which is the same as Geography, right? If so, can we have common name: either CoordinatesorGeography` to clearly see what was filtered?

@Dairus01 regarding point 7 in the message above, after discussion with @Pyatakov, he said that we probably won't need search by Schema since this is not that obvious thing, and moreover, this is not obvious on the UI, do we search by Schema ID or Schema Name. And in general, would be better to remove this parameter at all.
Also regarding the second part of the matching parameter names in filters and column names on a table, what is the difference between Geography filter parameter and Coordinates column name in table? Is it the same, just different namings?
