Schema update

[jm-rivera]

This pull request updates the oda_data package to version 2.3.1, introducing new donor and recipient mappings, expanding sector and purpose code support, and improving type handling and sector aggregation logic. It also updates dependencies and fixes several naming and mapping issues for greater consistency and robustness.

Key changes:

Provider/Donor and Recipient Mappings:

• Added the European Investment Bank (EIB, code 919) to provider/donor mappings across DAC1, DAC2A, CRS, and provider groupings (dac1_names.json, dac2a_names.json, crs_names.json, provider_groupings.json). [1] [2] [3] [4]
• Introduced new unspecified regional recipient codes: Southern Asia (6790), Micronesia (8600), Middle Africa (10280), Melanesia (10330), Polynesia (10350) in recipient groupings and CRS names (recipient_groupings.json, crs_names.json). [1] [2] [3] [4]

Sector and Purpose Code Enhancements:

• Added broad sector categories for top-level aggregation: Education, Health, Energy, General Environment Protection, Agriculture and Forestry & Fishing. Updated sector_lists.py to support these, including new groupings and mappings for aggregation. (F5eb2bc6L5R7, [1] [2] [3] [4] [5] [6] [7] [8]
• Expanded sector/purpose mappings to include Conflict/Peace/Security (152), Trade Policies (331), Refugees (930), Humanitarian Aid (700), and improved fallback mapping for unmapped sectors (crs_names.json, sector_lists.py). [1] [2] [3] [4]

Bug Fixes and Data Consistency:

• Fixed type conversion for code columns (sector_code, purpose_code, donor_code, agency_code) when adding name columns to handle mixed types (add.py).
• Corrected typos and capitalization in sector and group names, e.g., "Unallocated/ Unspecificed" → "Unallocated/ Unspecified", "government & Civil Society" → "Government & Civil Society" (sector_lists.py, crs_names.json, test_sector_lists.py). [1] [2] [3]

Dependency Updates:

• Updated package dependencies and development tools to newer versions in pyproject.toml, including oda-reader, pydeflate, uv-build, pre-commit, ruff, and mkdocs-material. [1] [2] [3]

Documentation:

• Updated CHANGELOG.md to reflect all new features, fixes, and enhancements in version 2.3.1.
