fix(user): resolve /user/avatar info query timeout via canonical JID

[cesar-carlos]

Description

POST /user/avatar hangs ~75s and returns HTTP 500 with "info query timed out" even when the instance is connected and message send/receive works.

Root cause (original)

CreateJID / ParseJID build phone JIDs with a leading + (e.g. +5566...@s.whatsapp.net).
GetProfilePictureInfo sends a raw IQ with Target: jid. WhatsApp does not accept that + on this path, so the IQ never gets a response and whatsmeow surfaces ErrIQTimedOut (info query timed out).

This is the same class of bug already fixed for reactions / typing / read receipts via utils.CanonicalJID.

What changed

1. In GetAvatar, after ParseJID: jid = utils.CanonicalJID(jid).ToNonAD() before GetProfilePictureInfo.
2. Addendum 18/jul (production Chatwoot report): bound avatar IQ to 8s using c.Request.Context(), map ErrIQRateOverLimit → HTTP 429, map IQ/context timeout → HTTP 504. Clients with ~12s read timeouts no longer hang on a ~80s server wait.

Before / after

	Before	After
POST /user/avatar (+ JID)	500 "info query timed out" ~75s	200 with url in ~0.1–2s
Slow/bad query	hang until ~75–80s	504 within ~8s
WA rate-overlimit	HTTP 500	HTTP 429

Related Issue

Closes #76

Type of Change

• Bug fix (non-breaking change which fixes an issue)

Testing

• Manual testing completed (canonical JID path)
• Unit test for HTTP status mapping (writeUserWAError)
• No breaking changes for expected WA errors (no picture / hidden → still 500)

Checklist

• My code follows the project's style guidelines
• I have performed a self-review of my code
• I have tested my changes thoroughly
• Single concern (avatar timeout/status); no drive-by refactors

Additional Notes

Follow-up PR #121 adds PictureURL on POST /user/info, LID→PN resolve, and docs for canonical query order.

Canonicalize JID before calling GetProfilePictureInfo to prevent avatar info query timeouts.	Apply utils.CanonicalJID to the parsed JID in GetAvatar to strip the leading '+' and convert to non-AD form before sending the raw IQ Add explanatory comment documenting the RAW IQ behavior and its relationship to previous typing/receipts bugs	pkg/user/service/user_service.go
Improve error handling and logging when GetProfilePictureInfo fails.	Wrap GetProfilePictureInfo errors with fmt.Errorf and %w, including the JID in the message for clearer diagnostics Retain existing error logging while returning a more descriptive wrapped error	pkg/user/service/user_service.go

**🚨 suggestion (security):** Revisit including the JID in the wrapped error for potential PII exposure.

Embedding the JID in the returned error introduces user-identifying data that may surface in logs or external error messages. Consider omitting or masking the JID in the error text, and if you need it for debugging, log it separately at an appropriate level while keeping the returned error generic.

Reopened — keeping this PR available for upstream review/merge.

Updated after production avatar failure report (Chatwoot account enrichment):

• Cap /user/avatar at 8s (request context) so clients with 12s ReadTimeout get 504 instead of hanging
• Map WhatsApp rate-overlimit → HTTP 429
• Keep canonical-JID fix for the original ~75s info query timed out (/user/avatar #76)

Please re-review the new commit on this branch.

[cesar-carlos]

Follow-up improvements from review:

• Resolve @lid → PN via LID store before profile picture IQ (when mapping exists)
• Replace fixed Sleep(2s) after StartInstance with context-aware ready poll
• Map context.Canceled → HTTP 504
