Add profile editor, member invite and status banners (#4)

* feat(healthchat): add profile editor, member invite and status banners

Native 13-field profile editor with diff-only saves and avatar upload
through the HealthChat API (replaces the upstream display-name editor),
email invitation for approved accounts, and non-dismissible account
status banners in settings and the member directory.

* fix(healthchat): satisfy detekt and konsist rules

Konsist presenter helper shape, no '=' in state parameter docs, present-tense invite callback, and complete renderer KDoc.
