Fix Manage Conversations Count

[ofilson]

Bug: "x of 20 selected" always shows 20 regardless of actual conversation count

Description

On the Manage Conversations page, the selection info bar displays:

0 of 20 selected

The denominator is always 20 (the MAX_SELECTION bulk-delete limit), even when the user has fewer than 20 total conversations. For example, if a user only has 5 conversations, the bar should read 0 of 5 selected, not 0 of 20 selected.

Steps to Reproduce

1. Have fewer than 20 conversations (e.g. 5).
2. Navigate to Manage Conversations.
3. Observe the selection info bar.

Expected Behavior

The denominator should be min(totalConversations, MAX_SELECTION):

• 5 conversations → 0 of 5 selected
• 30 conversations → 0 of 20 selected

Actual Behavior

The denominator is always 20 regardless of how many conversations exist.

Root Cause

In frontend/ai.client/src/app/manage-sessions/manage-sessions.page.ts, the template uses:

{{ selectedCount() }} of {{ maxSelection }} selected

maxSelection is a constant set to MAX_SELECTION (20). There is no computed signal that accounts for the actual number of loaded sessions. The denominator should be something like:

readonly selectableCount = computed(() => Math.min(this.sessions().length, this.maxSelection));

And the template should use selectableCount() instead of maxSelection.

Affected Component

• File: frontend/ai.client/src/app/manage-sessions/manage-sessions.page.ts
• Section: Selection Info Bar template + component signals

Additional Context

The same maxSelection value is also used in the page subtitle ("You can delete up to 20 conversations at a time"), which is correct since that describes the feature limit. Only the selection counter denominator needs to change.
