feat(app/email): consolidate queries package + block-email using tanstack query

[synoet]

• start consolidation of queries into a single queries package
• setup query-key-factory for better query key management
• previously we did two seperate queries every time we opened an email. The first would fetch the first page of the thread and check access in the definition. The second would create a complicated resource with pagination. Both of these are now consolidated into a single tanstack query. Via useEmailThreadQuery and its imperative alternative fetchAndCacheEmail both preserve the original errors from the api client using conversion between MaybeResult and a throwable error. Since they use the same query hook and key, the initial fetch inside the block definition will pre-populate the same underlying query as the one in the email block.
• add common email query and mutations, and port their original counterparts to use solid-query
