tooltip: PR review flags genuinely-missing tooltips instead of deferring to AA0218

Browse source 
The v1.4 policy deferred every missing-tooltip case to compiler analyzer AA0218. But AA0218 severity is per-app ruleset config and is routinely downgraded to info/None or disabled, so a genuine gap can ship unflagged. PR review is the last line of defence and should raise it independently.

Keeps the false-positive guard intact: a bound field whose source table field supplies a ToolTip still inherits it and is NOT flagged. Adds the genuinely-missing case (bound field whose source is also tooltip-less, or an unbound control) as a medium-severity finding. Updates both the ui inheritance article and the style AA0218 article.

Acceptable exceptions: table fields inside `Upgrade`, `Migration`, `HybridBC14`, `HybridSL`, and `HybridGP` codeunits and tables are allowed to omit the tooltip — those types are not surfaced to users.
AA0218 is a compiler analyzer, but its severity is configured per app in the ruleset and is frequently downgraded to `info`/`None` or disabled entirely. PR review therefore cannot assume the compiler will surface the gap: it is the last line of defence for a missing tooltip and should flag it independently. The one case review must *not* flag is a bound field that inherits a `ToolTip` from its source table field — see `bound-page-field-inherits-source-field-tooltip`.
## Best Practice
Every field control on a regular page carries `ToolTip = 'Specifies …';` (or a clear alternative phrasing). Compose the text in the form "what this value shows" rather than "what the user does with it".
Every field control on a regular page carries `ToolTip = 'Specifies …';` (or a clear alternative phrasing). Compose the text in the form "what this value shows" rather than "what the user does with it". In review, raise a `medium`-severity finding for a field that has neither an inline nor an inherited tooltip, independently of whether AA0218 is active in the app's ruleset.
See sample: `tooltip-required-on-page-fields.good.al`.
