fix: resolve_hostname endianness on little-endian MIPS

[AndrewAltimit]

Summary

• resolve_hostname used to_be_bytes() on the u32 IP returned by sceNetResolverStartNtoA, which double-swaps the bytes on little-endian MIPS (PSP Allegrex)
• The resolver stores the IP in network byte order (big-endian) in memory. Reading it as a u32 on LE gives a byte-swapped value. to_be_bytes() swaps again, reversing the IP (e.g. 207.241.224.2 becomes 2.224.241.207)
• Fix: to_ne_bytes() returns the raw memory bytes, which are already in the correct network order

Verified on hardware

• Before fix: all TLS connections failed (connecting to reversed IPs)
• After fix: DNS resolves correctly, TCP connects to archive.org CDN nodes succeed

Test plan

• Verified correct IP resolution on PSP hardware (archive.org -> 207.241.224.2)
• TCP connections to resolved IPs succeed
• No regression on HTTP streaming (channels using HTTP CDN still work)

Notes

• Fixes an IP address byte-reversal bug occurring on little-endian MIPS (Allegrex).
• to_ne_bytes() correctly retrieves the raw network-order bytes from memory, avoiding the reversal that to_be_bytes() introduced when operating on the u32 register value.
• The added documentation accurately explains the interaction between the PSP OS memory layout and the CPU's endianness.
