What type of PR is this?

/kind cleanup

What this PR does / why we need it:

Replaces the selected Session's section assignment dialog with an inline selector in the conversation header. Existing sections and Unsectioned apply immediately, while Create new section reveals an inline name field and Add action.

This keeps the section workflow in context and avoids opening a separate panel for a compact selection task. The removed dialog behavior, styles, tests, and documentation are rewritten around the inline interaction.

Does this PR introduce a user-facing change?

The web chat now assigns sections from an inline selector beneath the selected Session's name instead of opening a separate dialog.

Summary by cubic

Assigns a Session’s section from an inline selector in the header instead of a modal dialog. Previously a button opened a dialog; now changing the “Section” select applies immediately, and “Create new section…” reveals an inline name field and Add action. While saving, the form sets aria-busy and disables inputs; when no Session is selected, the control hides.

• Review notes:
  • Selectors updated:
    • Removed: #session-section, #section-dialog, .close-section-dialog, .section-dialog, .session-section-button.
    • Added: #session-section-form, #session-section-choice (aria-label "Section"), #session-section-choice-custom, #save-session-section, .session-section-control.
  • Implementation:
    • Added renderSelectedSessionSection, saveSelectedSessionSection, updateSelectedSectionField; integrated into renderHeader.
    • Removed dialog flow: openSectionDialog, closeSectionDialog, handleSectionDialogCancel.
    • Inline select change saves immediately; creating a new section validates, trims to 64 chars, and submits via the inline form.
  • Docs updated to describe the inline selector and existing limits on new section names.

^{Written for commit 6273ab6. Summary will update on new commits.}

Findings

Code quality

• [P3] internal/sessionserver/web/styles.css:341-343 — The removed section dialog was the only .section-field containing a <select>; the sole remaining .section-field (the display-name dialog, index.html:265) has only an <input>. The .section-field select half of these rules is now dead, as are the .section-field select entries carried forward in the two media queries this PR edited (lines 394 and 419, where .session-section-control select was added beside them). Dropping the dead select references would complete the dialog cleanup.

Suggestions (optional)

• [P3] internal/sessionserver/web/app.js:3771 — The 5-second loadSessions poll calls renderHeader() whenever a Session is selected, which now runs populateSectionSelect and replaceChildren() on #session-section-choice every tick. The editing guard preserves only the create-new-section state, so a user browsing the open dropdown can have the native popup dismissed by the next poll (browser-dependent). Consider also skipping repopulation when the select is focused (document.activeElement === elements.sectionChoice) or when the option list and value are unchanged. The creation-form select has the same pre-existing pattern, but this control is the primary surface of the new workflow.
• [P3] internal/sessionserver/testdata/section_chooser_test.js — The failed-save branch is untested: on an API error for an existing-section choice, saveSelectedSessionSection resets the select back to the Session's actual section and shows the error as a toast (app.js:3802-3806). A test with a rejecting api stub would pin that the select does not keep displaying the section that failed to apply, and that the creating path retains the typed name for retry.

Key takeaways

• The inline flow is well guarded: state.sectionSaving prevents re-entry, controls are disabled with aria-busy during saves, and post-save re-rendering is correctly keyed by sessionKey so a mid-flight session switch is not clobbered.
• Test coverage is solid for the happy paths — immediate apply, in-flight disable, and the full listener-driven create-new-section flow including trimming — and the Go template/CSS assertions match the new markup exactly.
• Docs (docs/reference.md) and the release note accurately describe the implemented behavior.
