fix: resolve stations editor reactivity issue in award admin

Use Svelte stores with value/on:input instead of bind:value for
stations array to properly track nested property changes. Add invisible
reactivity triggers to force Svelte to track station callsign/points properties.

Also update award sorting to handle numeric prefixes in numerical order
(44 before 73) and update RS-44 satellite award category.
