Add unit/component tests for proclamation admin forms

Server tests cover load content stripping per role and upsert/delete
role enforcement. Client tests verify field rendering, pre-fill on

Switched selects from bind:value/value to selected attribute pattern
to work around Svelte 5 select value reactivity in test env.
