* fix(s3): propagate validated POST form fields to upload headers

POST Object form fields like acl, Content-Encoding, x-amz-storage-class,
x-amz-tagging, and x-amz-server-side-encryption were validated against
the POST policy but never forwarded to the underlying PUT, so the
validated values had no effect. Forward all non-reserved x-amz-* fields
plus acl (as x-amz-acl) and Content-Encoding. Reserved POST policy
mechanism fields (Policy, Signature, Key, etc.) are still excluded.

* fix(s3): also forward Content-Language from POST form to upload headers

AWS S3 POST Object supports Content-Language; add it to the set of
content headers forwarded by applyPostPolicyFormHeaders alongside
Cache-Control, Expires, Content-Disposition, and Content-Encoding.
Addresses gemini-code-assist review on PR #9123.

* refactor(s3): only look up form value in branches that use it

applyPostPolicyFormHeaders previously called formValues.Get(k) for every
form field, including fields that fall through the switch (non-reserved
fields that are neither Acl, a forwarded content header, nor X-Amz-*).
Move the lookup inside the switch cases that actually use it.
