fix: correct spelling mistakes in comments and field name

[crawfordxx]

Fix multiple typos found across the codebase:

• response.go: rename unexported field commited to committed and fix related comments
• server.go: fix addres to address in comment
• middleware/csrf.go: fix formated to formatted in comment
• middleware/request_logger.go: fix commited to committed in comment
• echotest/context.go: fix wil to will in comments (2 occurrences)

All changes are either in comments or in an unexported (internal) struct field name. No behavioral changes.
