safeFetch already returns parsed JSON and throws on non-2xx — callers were
treating the result as a Response object and checking .ok / .json(), which
made votes, comment votes, and comment posts silently fail every time.
Also: fetchProposals was missing cache:'no-store' so newly posted proposals
were invisible until the 24hr browser cache expired; getProposals was sending
24hr Cache-Control so Cloudflare CDN served stale data; getShareableImageUrl
had a double slash (/api//petition-svg); wrangler.toml had an invalid [pages]
stanza that caused a warning on every deploy.
