Add {.topic} markup for non-function help page references

Replace {.code ?AMR-options} and backtick-style ?AMR-options / ?AMR-deprecated
references with proper {.topic AMR-options} / {.topic AMR-deprecated} cli markup
in count.R, interpretive_rules.R, proportion.R, and zz_deprecated.R.

Add {.topic} fallback handler to format_message() in aa_helper_functions.R:
plain-text environments render {.topic foo} as ?foo, and the [text](topic)
link form extracts just the display text (same pattern as {.help}).

Also convert remaining backtick function/arg references in proportion.R to
{.help [{.fun ...}](AMR::...)}, {.arg}, and {.code} markup for consistency.

Note: zzz.R intentionally keeps the backtick form since its startup message
goes through packageStartupMessage() which bypasses our cli infrastructure.
