A rabbit maps the provinces wide,
With meridians set side by side.
TM-3 and UTM join the chart,
Safe PROJ strings play their part.
The dialog shows each choice with care,
While bunny hops through grids of air.

including converting đ, before matching place names, so inputs such as “Hà Nội”
match the existing hanoi alias; preserve the current normalization and
supported-name behavior for other inputs.
Review comments at @crates/ui-egui/src/dialogs.rs:
- Line 1240: Update the preset resolution flow before rendering preset_fields so
a resolved place name such as hanoi is converted to its preset code before the
VN-2000 check; use that resolved code to show the province buttons and
central-meridian field.

- rustgis-data's vn2000_epsg() is now the one table of VN-2000 system
names. Crs::parse and the map's presets both use it, so a name one
takes (vn2000_utm48, VN200048, VN-2000 / UTM zone 49) the other takes
too. A test checks the two agree.
- Crs::parse reads a PROJ string only when it starts with "+proj=",
not any text starting with "+proj" ("+project…").
- The Coordinate System dialog no longer reads a bare word such as
"hue" or "vinh" as a province. Like map.projection, it needs the
vn2000: prefix (vn2000:hanoi). The test checks bare names stay as
typed and the ambiguity message for a bare "vn2000".

- validate_proj_string refuses any key with "grid" in it (vgrids, xy_grids, z_grids, gridlist as well as nadgrids, geoidgrids, grids), +step and +proj=pipeline, besides init, file and catalog. Tests cover them. - PROJ strings typed into Crs::parse (commands, the dialog) get their own cap of 256 entries in the custom table, so they cannot use up the room files' own coordinate systems need. - One squash() helper normalises VN-2000 names for is_bare_vn2000, vn2000_epsg and Crs::parse; parse_preset matches the name once, not once per preset. - The VN-2000 rows in vi.tsv sit in sorted order; a stray blank line in lookup is gone.

… key check - Crs::parse registers a typed PROJ string through Crs::register, which checks MAX_TYPED under the same lock as the insertion, so concurrent callers can't overshoot it. - proj_key_refused() is the one check for PROJ keys that read files or build pipelines, used for typed definitions and for those handed to GDAL's programs, whose list now refuses every grid key (vgrids, xy_grids...) and pipelines as well.
