- Migrated to Pydantic v2:
  - Replaced deprecated `parse_obj()` and `parse_raw()` with
`model_validate()` and `model_validate_json()`.
  - Replaced `.dict()` with `.model_dump()` for serializing models to dictionaries.
  - Updated `validator` to `field_validator` and `root_validator` to
`model_validator` to comply with Pydantic v2 syntax changes.

- Fixed asyncio issues:
  - Added `await` for asynchronous methods like `raise_for_status()`
in `RemoteAccount` and other HTTP operations to avoid `RuntimeWarning`.

- Updated config handling:
  - Used `ClassVar` for constants in `Settings` and other configuration classes.
  - Replaced `Config` with `ConfigDict` in Pydantic models
to follow v2 conventions.
  - Added default values for missing fields in chain configurations
(`CHAINS_SEPOLIA_ACTIVE`, etc.).

- Adjusted signature handling:
  - Updated the signing logic to prepend `0x` in the `BaseAccount` signature
generation to ensure correct Ethereum address formatting.

- Minor fixes:
  - Resolved issue with extra fields not being allowed by default
by specifying `extra="allow"` or `extra="forbid"` where necessary.
  - Fixed tests to account for changes in model validation and
serialization behavior.
  - Added `pydantic-settings` as a new dependency for configuration management.

- Updated all instances of **extra_fields to ensure proper handling of
Optional dictionaries using `(extra_fields or {})` pattern.
- Added proper return statements in `AlephHttpClient.get_message_status`
to return parsed JSON data as a `MessageStatus` object.
- Updated `Settings` class in `conf.py` to correct DNS resolvers type
and simplify the `model_config` definition.
- Refactored `parse_volume` to ensure correct handling of Mapping types
and MachineVolume types, avoiding TypeErrors.
- Improved field validation and model validation in `SignedPubKeyHeader` by
using correct Pydantic v2 validation decorators and ensuring compatibility with the new model behavior.
- Applied formatting and consistency fixes for `model_dump` usage and indentation improvements in test files.

…Pydantic v2 requirements

Pydantic v2 requires explicit type annotations for fields, so added `float`
to ensure proper validation of HTTP_REQUEST_TIMEOUT.

There were changes made on aleph-message on the main branch about
pydantic version. Using the version by the url and then change it
later after the release.

Using List from typing instead to assure the compatibility between python3.8 and above

Changing the version from the branch to the main of aleph-message
mypy rose some errors about missing name argument, so setting the as None because
they are optional

- Move/improve flow code parts from CLI to SDK
- Add utils functions
- Add `make_instance_content` and `make_program_content`
- Refactor `create_instance` and `create_program`
- Add `get_estimated_price`
- Fixes for mypy/ruff/pytest
- Minor improvements
- Remove firecracker rootfs hashes for instances
