* feat(auth): make auth token TTL configurable via AUTH_TOKEN_TTL env var
Add AUTH_TOKEN_TTL environment variable (in seconds) to override the
hardcoded 30-day auth token lifetime. Self-hosted deployments on trusted
networks can set a longer value to avoid frequent magic-link
re-authentication.
The value is read once at startup and cached. Invalid or missing values
fall back to the 30-day default with a warning log.
Closes#2685
* refactor(auth): extract parseAuthTokenTTL for testability
Address review feedback: extract pure parse function from sync.Once
wrapper so the parsing logic can be unit-tested independently.
Add TestParseAuthTokenTTL with table-driven cases.

* refactor(auth): accept Go duration strings + hoist shared TTL in SetAuthCookies
Address nice-to-have review feedback from Bohan-J:
- parseAuthTokenTTL now tries time.ParseDuration first (e.g. '8760h'),
falling back to ParseInt for integer seconds
- Warn on unreasonable values (>10 years) but still accept them
- Hoist AuthTokenTTL() and time.Now() in SetAuthCookies so both
cookies share the exact same expiry
- Add security trade-off note in .env.example
- Add 5 new test cases for duration strings

* fix: use AuthTokenTTL() in CloudFront middleware, guard ParseInt overflow
Address review feedback from Bohan-J (round 2):
1. CloudFront refresh middleware (cloudfront.go:21) was hardcoding
30*24*time.Hour instead of using auth.AuthTokenTTL(). Now calls
AuthTokenTTL() so the middleware respects AUTH_TOKEN_TTL env var.
2. parseAuthTokenTTL integer-seconds branch: very large values like
9999999999 would silently overflow int64 when multiplied by
time.Second. Added overflow guard comparing against
math.MaxInt64/int64(time.Second) before the multiplication.
3. Updated AuthTokenTTL() doc comment to reflect that it accepts
Go duration strings or integer seconds (not just seconds).
4. Added middleware test (cloudfront_test.go) verifying short
AUTH_TOKEN_TTL produces short cookie expiry, not 30-day hardcode.
Also covers nil signer and existing-cookie-skip cases.
5. Added integer overflow test case to cookie_test.go.
* style: run gofmt on cookie.go and cookie_test.go

- Add CloudFront cookie refresh middleware so cookies are re-issued when expired
- Log errors in groupAttachments instead of silently swallowing them
- Move useFileUpload hook to shared/hooks/ per project architecture conventions
- Add uploadWithToast helper to deduplicate try/catch/toast pattern across 3 components
- Refactor ApiClient.uploadFile to reuse auth headers, 401 handling, and error parsing
- Allow empty MIME types client-side (let server sniff and decide)
- Constrain Image extension max-width in rich-text-editor to prevent layout overflow
