{.topic} in cli requires a package-qualified topic reference to generate
a valid x-r-help:pkg::topic URI. Bare {.topic AMR-options} produced a
malformed x-r-help:AMR-options URI (no package prefix).
Use the [display_text](pkg::topic) form throughout:
{.topic [AMR-options](AMR::AMR-options)}
{.topic [AMR-deprecated](AMR::AMR-deprecated)}
The hyphen in the topic name is fine as a URI string even though
AMR::AMR-options is not a valid R symbol expression.
The fallback handler in format_message() already handles the [text](uri)
form by extracting the display text, so plain-text output is unchanged.

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.
