feat: make max request size configurable

[TorstenDittmann]

The /analyze body limit was hardcoded at 10 MiB. It is now set with MAX_REQUEST_SIZE so operators can raise or lower it without rebuilding.

Default: 10MiB (10485760 bytes), including multipart overhead.

Examples:

# default remains 10 MiB
./autogravity

# larger uploads
MAX_REQUEST_SIZE=32MiB ./autogravity

# exact byte count
MAX_REQUEST_SIZE=10485760 ./autogravity

Accepted values are a positive integer (bytes) or a size with a KiB/MiB/GiB or KB/MB/GB suffix. Oversized requests still return 413, with the configured limit in the error message.

Decoded-image megapixel limits are unchanged.

The PR appears safe to merge because no unresolved blocking behavior or accepted new finding remains.

Summary

• Parses positive byte counts and common decimal or binary size suffixes.
• Applies the configured limit to request-body enforcement and reports it in oversized-request errors and startup logs.
• Adds behavior-level request-limit tests and documents the setting in the README and documentation site.
