chore: lint fixes part 2

[pawbana]

• var-naming: HttpErr → HTTPErr, inputJson → inputJSON, strJson → strJSON, Name_ → NameStr (Go naming conventions)
• var-declaration: removed redundant []string type annotation
• unconvert: removed unnecessary string() conversion
• sprintfQuotedString: "%s" → %q (4 locations)
• elseif: else { if } → else if
• early-return: inverted conditions to eliminate else blocks (3 locations)
• superfluous-else: removed else after break/continue (2 locations)
• unnecessary-stmt: single-case switch → if type assertion (4 locations)
• empty-block: added nolint directive for intentionally swallowed panic recovery
