Update Dependencies within `pyproject.toml` to Include Ranges

[harryswift01]

We need to update the dependency definitions in pyproject.toml to use version ranges instead of pinned == versions. This change will allow Renovate to detect outdated dependencies, propose safe upgrades, and manage ranges accurately using the configured rangeStrategy: replace.

Changes Needed

• Replace strict == pins with compatible range specifiers (e.g., >=x.y,<x+1.0)
• Apply ranges to:
  • project.dependencies
  • project.optional-dependencies (testing, pre-commit, docs)
• Ensure all dependencies have a valid version constraint so Renovate can track them
