Update custom icon font with new designs

[j0ntz]

Description

Regenerates the fontello custom icon font from the designer SVGs attached to
the Asana task, which asked
for the app's custom icons to be brought in line with the updated design ("we just need
to fix the inconsistencies we have").

Five existing glyphs are replaced in place, keeping their name and codepoint so every
call site picks up the new artwork with no code change:

Glyph	Where it renders
buy	Buy bottom tab
sell	Sell bottom tab
sort	Assets wallet-list header sort button
control-panel-scan-qr	Side menu, Scan QR
control-panel-fio-names	Side menu, FIO Names

The sixth SVG is a chart icon, which the font did not have. It lands as a new chart
glyph and replaces the FontAwesome chart-line on the side menu's Markets row: that
solid glyph was the odd one out in an otherwise all-outline menu, which is the kind of
inconsistency this task is about.

The font is rebuilt through the fontello session API rather than by hand. Posting the
checked-in config.json back to it reproduces the committed custom.ttf byte for byte
apart from the head timestamps, table checksum and version string, so the only outline
changes in this diff are the six intended glyphs. android/app/src/main/assets/fonts/custom.ttf
is the only font file: ios/edge.xcodeproj/project.pbxproj references that same path,
so iOS and Android share it.

Requirements

If you have made any visual changes to the GUI. Make sure you have:

• Tested on iOS device
• Tested on Android device
• Tested on small-screen device (iPod Touch)
• Tested on large-screen device (tablet)

Driven on the iOS 18.6 simulator: the Assets scene (Buy / Sell tabs and the wallet-list
sort button) and the side menu (FIO Names, Scan QR, Markets). Screenshots below.

Note

Low Risk
Visual-only icon font and one side-menu icon source change; no business logic, auth, or data handling.

Overview
Refreshes the Fontello custom icon font so several in-app glyphs match the updated outline design while keeping the same names and codepoints (buy, sell, sort, control-panel-scan-qr, control-panel-fio-names), so existing iconName usages pick up new artwork without call-site changes.

Adds a new chart glyph and updates SideMenu so the Markets drawer row uses iconName: 'chart' instead of FontAwesome chart-line, aligning that row with the rest of the outline side menu icons.

CHANGELOG.md documents the icon refresh.
