[3.0] Centres the forum title and logo in the header

[albertlast]

Description

Two rules in index.css are leftovers from the header as it was before #9373, when it was a band of its own that bottom-aligned its contents:

h1.forumtitle { padding: 22px 12px 6px 10px; }
img#smflogo   { margin: 16px 0 0 0; }

The header lines its contents up in the middle now (#header .content_wrapper { align-items: center }), so both of those push the title and the logo below the user panel sitting beside them. Measured centres on the board index at 1280px, before and after:

	wrapper	title	logo	user panel
before	47	47	55	47
after	47	47	47	47

The title keeps the horizontal padding that lines it up with the page content below it — as padding-inline, so the RTL sheet does not need its own rule. Its start edge stays at x=76 against the breadcrumb's 75. The logo needs nothing; RTL's own img#smflogo { margin-right: 1em } still applies.

Header height is unchanged at 93px either way — --header-height: 80px sets the floor.

This is the visible half of what #9423 reports. The rest of that report is the intended layout from #9373 and #9374, which merged the old #top_section into the header; that matches the end state of #7933 and is not changed here.

Superseded by #9427. That one puts the header back to a band of its own between the top bar and the menu, per the decision on #9423, so the row this centred things in no longer exists — the top-heavy padding on h1.forumtitle and the top margin on img#smflogo are correct again against align-items: flex-end. Nothing here to carry over.
