Fix assorted code-review issues across capture, cont3xt, and CI (#4032)

- reader-scheme-s3.c: guard NULL endNext before pointer compare; reset s3Items->done in scheme_s3_load_full_dir so listings and continuation pages aren't skipped
- python.c: add ARKIME_PY_HANDLE guard so invalid opaque handles raise a Python exception instead of dereferencing NULL
- parsers/imap.c: buffer partial lines per-direction to avoid concatenating client/server data under the wrong direction
- parsers/dns.c: emit RFC 3597 CLASS%u/TYPE%u for unknown query class/type and omit reserved 0 instead of printing "(null)"
- writer-simple.c: size the mmap output buffer via ARKIME_SIMPLE_BUFSIZE (pcapWriteSize + max packet + record header)
- parsers/isis.c: use "Msg Type" friendly name for isis.msgType
- reader-scheme-file.c: drop bogus "Receive Error" from the opendir failure message
- arkime.h: type reloadFunc as ArkimePluginReloadFunc to match the definition
- cont3xt: add safeUrl sanitizer and use it for integration external link/url hrefs
- .github/workflows: pass release/snapshot inputs via env vars and validate them to avoid injection
- tests/pcap/v6-http.test: update DNS baseline for the class/type change
