[Utility] Minimum staking values for each actor

[Olshansk]

Objective

Introduce a minimum stake (MinStake) requirement for Gateways, Suppliers, and Applications in the network.

Origin Document

In Morse, if you run:

    curl --location -X 'POST' -H 'Content-Type: application/json' "${POCKET_ENDPOINT}/v1/query/allParams" | jq

We find the following param under node_params

    {
      "param_key": "pos/StakeMinimum",
      "param_value": "15000000000"
    },

Goals

• Establish a clear MinStake requirement for Gateways, Suppliers & Applications
• Enhance network security and reliability by having "something at stake"
• Create AT LEAST Morse feature parity

Deliverables

• [ ] Add the MinStakeGateway governance parameter
• [ ] Add the MinStakeApplication governance parameter
• [ ] Add the MinStakeSupplier governance parameter
• [ ] Update docusouras documentation on these params
• [ ] Add at least one minimum E2E and unit test for each
• [ ] Communicate the changes to the network participants.

Non-goals / Non-deliverables

• Implementing any staking-related penalties or rewards beyond the initial MinStake requirements.
• Making changes to the staking mechanisms unrelated to the MinStake values.
• Addressing any other network roles not specified in this issue (e.g., Validators).

General deliverables

• [ ] Comments: Add/update TODOs and comments alongside the source code so it is easier to follow.
• [ ] Testing: Add new tests (unit and/or E2E) to the test suite to ensure MinStake enforcement.
• [ ] Makefile: Add new targets to the Makefile to facilitate testing and deployment of MinStake functionality.
• [ ] Documentation: Update architectural or development READMEs; use mermaid diagrams where appropriate.
