feat(meeting-types): let owners write the note bookers already see

[asm0dey]

Closes #128.

What was actually wrong

MeetingType.description has been in the schema since V1__core_schema.sql:15 and renders in two public places already — the booking page's left rail (book.html:40) and the public landing card (landing.html:21). But no form ever wrote it. The column was permanently NULL for every user, and both renders were unreachable branches.

So #128 isn't "add a note field" — it's "expose the note field that already exists".

Loading

Everything to the right of the column already shipped. Nothing on the left existed — no form wrote
the column, so it was NULL for every user and all four read paths were dead. This PR adds only
the left half.

Change

• AdminResource.applyEditableFields takes a description and writes it (blank → null); create and edit already share that method, so both paths get it from one line.
• @RestForm String description on createMeetingType and editMeetingType.
• Textarea on the create form (meetingTypes.html) and the detail page's Basics section (meetingTypeDetail.html), maxlength="2000".
• New i18n key adm_meetingTypes_label_description with de + he values.
• No migration. The column is already there.

Placement: the note stays in the left rail where it already rendered, not in the booking-form column the reporter's screenshot pointed at. It sits under the type name and duration, above the fold, and stacks first on mobile. Easy to move if the reporter disagrees once they can actually see it.

Worth knowing

Booking.effectiveDescription(type) falls back to the type's description (BookingService.java:608), so this note also becomes the Google Calendar event body and the .ics DESCRIPTION for every booking of that type. That's arguably the right behaviour for "please don't worry if you're late", but it isn't note-on-the-page-only.

Tests

MeetingTypeDescriptionTest — 8 cases covering the round trip: admin form → column → public booking page and landing card, plus blank-clears-to-null and the edit path.

Full suite: 1044 tests, 0 failures, 0 errors, BUILD SUCCESS.

Folded-in dependency updates

This branch also carries the nine open Renovate PRs, merged in and validated together rather than
one at a time:

PR	Update
#169	quarkus.platform.version → 3.39.2
#170	surefire-plugin.version → 3.6.0
#167	com.google.api-client:google-api-client → 2.9.1
#166	git-commit-id-maven-plugin → 10.0.1
#165	spotless-maven-plugin → 3.10.2
#171	oven/bun:1 digest
#164	bellsoft/hardened-liberica-runtime-container:jre-distroless-musl digest
#163	bellsoft/liberica-runtime-container:jdk-26-musl digest
#162	bellsoft/alpaquita-linux-base:stream-musl digest

#169 and #170 both edited adjacent lines in pom.xml's property block, so that one merge conflicted;
resolved by keeping both bumps. Full suite re-run on the merged result: 1044 tests, 0 failures,
spotless:check clean.

Also in here: a Sonar java:S9358 fix on both meeting-type slug sites — the ternary chose between
two Slugs.slugify(...) calls instead of between the two inputs.
