Implement UV for dependency lock (#956)

* first uv sync

* explicitly set np.int64 dtype before calling pd set_index()

Pandas 2 got rid of the `Int64Index` class, it was downcasting to int32 for the input land use table

* Add all dependencies from Conda environments

Consider removing unused ones at a later time

* Remove orca

This dependency was replaced with “state” for workflow orchestration.

* Update release instructions for `uv`

* Remove `--no-default-groups` from `uv sync` instructions

* Trial updating Github Action to uv instead of conda

* Bug fixes

* Try downgrading sharrow

* change core test to windows runner

* use win for all core tests

* index type mismatch

* formatting

* unlock sharrow to 2.14

* correct a typo

* Update Model Setup page in user guide

* Update Ways to Run the Model page

* Remove duplicates

* Simplify pyproject.toml for github action and use only this group

* Update remainder of user guide docs

* Update dev guide [makedocs]

* Update lockfile from changes to dependencies

* Remove conda from other github actions

* Debug doc building [makedocs]

* Update install instructions [makedocs]

* update installation instructions [makedocs]

* notes on uv options [makedocs]

* address review comment
