Tracking issue: wasm crate tests

[Valentine1898]

We can't test wasm functions that use indexed-db global using vi.test so we have to write tests on rust with indexed-db mock

• Convert build_action() tests #1830
• Write tests for witness() #1831
• Write tests for authorize() #1832
• transaction_perspective_and_view() tests #1833
• Add rust tests for view_server.rs #694
• Write tests for save_metadata_if_needed() #1835
• Write tests for prioritize_and_filter_spendable_notes() #1836
• Planner tests: Output action #1837
• Planner tests: Swap action #1838
• Planner tests: Swap claim action #1839
• Planner tests: Delegate action #1840
• Planner tests: Undelegate action #1841
• Planner tests: Ics20Withdraw action #1842
• Planner tests: Position actions #1843
• Planner tests: Auction actions #1844
• Planner tests: test limit #1845
• Planner tests: memo #1846

@grod220 perhaps we should prioritize some effort on expanding test coverage for our wasm package in the near term?
